# Q 3.     To make a saturated solution, 36 g of sodium chloride is dissolved in 100 g of water at 293 K. Find its concentration at this temperature.

Given that,

Mass of solute (sodium chloride) = 36 g = $w_1$
Mss of water (as a solvent) = 100 g = $w_2$

Therefore, the total mass of solution = 100  + 36 = 136 g = $W$

According to question,
Concentration =  $\frac{w_1}{W}\times 100$
$=\frac{36}{136}\times 100$
$=26.47$ %

Hence the concentration of the solution at 293 K is 26.47%
