Question

To make a sarurated solution, 36 g of sodium chloride is dissolved in 100 g of water at 293 k . Find its concentration at this temperature

Answer 1

Answer:

The answer is "$26.47\%$"

Explanation:

Sodium chloride  solute mass$=36 \ g$

Solvent water mass$=100\ g$

Calculating the solution mass = Solute mass  + solvent mass

                                                  $= 36\ g +100\ g\\\\ = 136\ g$

Calculating the percentage of concentration:

$= \frac{solute\ mass}{solvent\ mass} \times 100\\\\=\frac{36\ grm}{136\ grm} \times 100\\\\=0.2647 \times 100\\\\=26.47 \%$
