20g of sodium chloride is dissolved in water to make up the volume of the solution to 250 ml.calculate the mass by volume percentage of sodium chloride in the solution
Answers
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 = = 8
Therefore mass by volume percentage = 8%
