What is the concentration in by volume?
In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration.
How do you find concentration from volume?
Divide the mass of the solute by the total volume of the solution. Write out the equation C = m/V, where m is the mass of the solute and V is the total volume of the solution. Plug in the values you found for the mass and volume, and divide them to find the concentration of your solution.
What is VOL VOL?
Volume/volume percentage (v/v percent) is a measure of the concentration of a substance in a solution. It is expressed as the ratio of the volume of the solute to the total volume of the solution multiplied by 100. Examples: Wine has a typical alcohol content (v/v percent) of 12 percent.
What is the volume solution?
Because a solution is comprised of both a solute and a solvent, the volume of a solution, as a whole, is equal to the sum of the volumes of the solute and the solvent that it contains. Therefore, the following equation can also be used to calculate the volume percent of a solution.
Is volume percentage dependent on temperature?
Volume is a temperature dependent quantity and hence it changes with change in temperature. Hence it is true that volume percentage depends upon temperature.
When to use volume percent or volume percent concentration?
Volume percent or volume/volume percent (v/v%) is used when preparing solutions of liquids. It is very easy to prepare a chemical solution using volume percent, but if you misunderstand the definition of this unit of concentration, you’ll experience problems.
Which is the final volume of a solution?
V is volume of solution in which the indicated mass (m) of solute must be dissolved to make the desired solution concentration (C). Note that V is the final or total volume of solution after the solute has been added to the solvent.
What’s the difference between volume V and volume m?
m is the mass (i.e., weight) of solute that must be dissolved in volume V of solution to make the desired solution concentration ( C ). V is volume of solution in which the indicated mass ( m) of solute must be dissolved to make the desired solution concentration ( C ).
When do you use mass per volume calculations?
Such concentration calculations are needed when starting with the solid form of a chemical and a solution needs to be prepared with the concentration unit expressed in unit mass per unit volume (such as mg/mL).
