Question

25g of solute is added in 75g of water. Calculate the mass percent of solute?

Answer 1

Answer:

25% is the correct answer.

Explanation:

Mass of solute, Common salt  = 25g

Mass of solvent, water = 75g

Substituting values in formula,

Concentration of solute in mass%=

mass of solute * 100/ (mass of solute + mass of solvent)  

%Common Salt =25*100/(75+25)

                       = 25%
