$1 g$ of $N a C l$ dissolved in $100 g$ of water to prepare a mixture. What is the mass percentage of sodium chloride?

Open in App

Solution

Mass of solute i.e, for the sodium chloride =58.5g
Mass of solvent i.e, for the water=100g
Mass of solution=58.5+100=158.5g
The concentration of solution in terms of mass percentage is given as,
$= \frac{M a s s o f s o l u t e}{M a s s o f s o l u t i o n \times 100}$

$= \frac{58.5}{158.5 \times 100}$

$36.9$
