Question

A solution contains 35 g of sugar and 15 g of sodium chloride salt in 450 mL of water. Calculate the mass per cent of (a) sugar (b) sodium chloride salt (density of water = 1 g /mL).​

Answer 1

Answer:

Answer

Mas of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

=360 g
