Question

If 105 g of copper sulphate is dissolved in 500 ml of water, calculate the mass by volume percentage of this solution.Plz answer

Answer 1

★ Answer :

Mass by volume % =

$\dfrac{Mass \: by \: solute(g)}{Volume \: of \:solution(ml)} \times 100$

Given :

Copper sulphate (mass of solute) = 105 g

Volume of water (volume of Solution) = 500 ml

Solution :

by putting the values..

Mass by volume % =

$\dfrac{105}{\cancel{500}} \times \cancel{100}$

$= \dfrac{105}{5} = 21$

$\leadsto \therefore \: mass \: by \: volume \: \% = 21 \%$

★ Additional Information:

Mass % = $\dfrac{Weight \: of \: solute(g)}{Weight\:of \: Solution(g)}$

Volume % = $\dfrac{Volume \: of \: solute(ml)}{Volume\:of \: Solution(ml)}$
