Is focus a verb or adjective?
Is focus a verb or adjective?
The adjective focused derives from the verb focus, which means to fix on a central point. When you are focused on school, all your attention is fixed on one thing: school. When your telescope is focused on Jupiter, you have aligned the lenses with where Jupiter is in the sky.

What is called Focus?
In geometrical optics, a focus, also called an image point, is a point where light rays originating from a point on the object converge. Since light can pass through a lens in either direction, a lens has two focal points – one on each side.
What is the importance of focus?
Focus is so important because it is the gateway to all thinking: perception, memory, learning, reasoning, problem solving, and decision making. Without good focus, all aspects of your ability to think will suffer.
Why focus is the key to success?
Focus is the key to success. You must focus on what you want in your life and go after that 110%. There will be times in life, when you will have distractions and obstacles but you must overcome them while maintaining your focus on your goal.
What is concentration and its importance?
Concentration is the ability to focus the attention on one single thought or subject, excluding everything else from the field of awareness. The ability to focus the attention is one of the most important abilities one should possess. However, most people lack the ability to concentrate.
What is concentration in simple words?
Definition. noun. (1) The measure of the amount of a sub-component (especially solute) in a solution. (2) The ratio of the mass or volume of a substance (solute) to the mass or volume of the solvent or solution.
How do you describe concentration?
In chemistry, concentration refers to the amount of a substance in a defined space. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration is usually expressed in terms of mass per unit volume.
How do you write concentration?
The standard formula is C = m/V, where C is the concentration, m is the mass of the solute dissolved, and V is the total volume of the solution.
What is an example of a concentration?
The concentration of the solution tells you how much solute has been dissolved in the solvent. For example, if you add one teaspoon to two cups of water, the concentration could be reported as 1 t salt per 2 c water. The vinegar label will report that the solution is 5% by weight acetic acid.
How do I calculate the concentration of a solution?
Rearranging the equation for concentration allows the mass of solute to be calculated:
- mass of solute in g = concentration in g/dm 3 × volume in dm 3
- A solution of sodium chloride has a concentration of 10 g/dm 3.
- mass of solute in g = concentration in g/dm 3 × volume in dm 3
- = 10 g/dm 3 × 2 dm 3
What units are concentration?
Some of the more common concentration units are:
- Mass per unit volume.
- Percent by mass.
- Percent by volume.
- Molarity.
- Normality.
- Molality.
- Parts per million (ppm).
- Parts per billion (ppb) This works like above, but we multiply by one billion (109:
What is number concentration?
The number concentration is defined as the number of entities of a constituent in a mixture divided by the volume of the mixture : The SI unit is 1/m3.
Is Molality a concentration?
Molality (m), or molal concentration, is the amount of a substance dissolved in a certain mass of solvent. It is defined as the moles of a solute per kilograms of a solvent.
Is g mL a concentration?
Thus 100 mL of water is equal to approximately 100 g. 1% m/v solutions are sometimes thought of as being gram/100 mL but this detracts from the fact that % m/v is g/mL; 1 g of water has a volume of approximately 1 mL (at standard temperature and pressure) and the mass concentration is said to be 100%.
What is the concentration of a 1% solution?
A one percent solution is defined as 1 gram of solute per 100 milliliters final volume. For example, 1 gram of sodium chloride, brought to a final volume of 100 ml with distilled water, is a 1% NaCl solution. To help recall the definition of a 1% solution, remember that one gram is the mass of one milliliter of water.
What is 35g in mL?
Convert 35 grams to ml 67 ml.
Is density equal to concentration?
Concentration is amount of a salute per unit volume of a solution while density is mass of something per unit volume. Concentration and density do not have the same units! Concentration = 1/Volume (e.g. mol/L) or %, ‰ or ppm, ppb, ppt, …
What is the concentration of water?
55.5 mol/L
How do I calculate molar concentration?
To calculate the Molar Concentration, we will find the molar concentration by dividing the moles by liters of water used in the solution. For example, the acetic acid here is completely dissolved in 1.25 L of water. Then divide 0.1665 moles by 1.25 L to get the molar concentration, which will be 0.1332 M.
How do you convert density to concentration?
Add the mass of the solute to the mass of the solvent. If the silver nitrate is dissolved in 70 grams of water: 30 + 70 = 100 grams. Divide this answer by the solution’s density. If its density is 1.622 grams per cubic centimeter: 100 / 1.622 = 61.65.
What is the formula for calculating density?
Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume.
Does density increase with concentration?
When we add solute to solution density of it increases, since increase in the mass of solution is larger than the increase in volume. In solid-liquid solutions, density increases with increasing in the concentration of solution.
How do I calculate pH?
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].
What is pH full form?
In chemistry, pH (/piːˈeɪtʃ/, denoting ‘potential of hydrogen’ or ‘power of hydrogen’) is a scale used to specify the acidity or basicity of an aqueous solution.
