Answer:

20g of sodium chloride is dissolved in 100ml of water

250ml is the volume of solution

to calculate mass by volume percentage :-

we know = mass of solute / volume of solution *100

= 20g/250 ml *100 = 8 percent of g/ml

Answer: The answer is 8 percent.

Mass by Volume Percentage: The mass/volume percent of a solution is the ratio of the mass of the solute that is present in a solution to the volume of the solution as a whole. This ratio is expressed as a percentage of the total volume of the solution. As a result of the fact that this kind of concentration is denoted by a percentage, the proportion that was given needs to be multiplied by 100,

Explanation:

Step 1: The given data:

Mass of sodium or solvent in the solution = 20g

Volume of the Solution = 250 ml

Step 2: Find the Mass by volume percentage

Mass by Volume Percentage = (Mass of solvent / Volume of solution)X100

Mass by Volume Percentage = \frac{20}{250}X 100\\ = 8

Therefore mass by volume percentage  = 8%
