Question

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

Answer 1

____________________


$\bold{Given:-}$

Mass of $NaCl_{2}$$= 36 g$


Mass of solution $= 36 + 100 = 136g$


$\bold{Now,}$


$\bold{We\:know\:that,}$


$Conc. \: of \: solution = \frac{Mass \: of \: solute}{Mass \: of \: solution} \times 100$


$Conc. \: of \: solution = \frac{36}{136} \times 100$


$Conc. \: of \: solution = 0.2647 \times 100$


$Conc. \: of \: solution = 26.47\%$


$\bold{Therefore,}$


It's concentration at this temperature is $26.47\%$

Answer 2

Answer :

Mass of solute (NaCl) = 36 g

Mass of solvent (H2O) = 100 g

Mass of solution (NaCl + H2O) = 136 g

Concentration = Mass of solute/Mass of solution x 100

Concentration = 36/136 x 100 = 26.47%

__________....

• Hence, the concentration of the solution is 26.47%
