Question

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

Answer 1

Answer:

Mass of solute=36g

Mass of solvent=100g

Mass of solution =100+36=136g

Concentration of solution=Mass of solute÷Mass of solution ×100

=36g÷136×100

=26.47%

Answer 2

Answer:

$\huge\tt\pink{Answer:}$

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%
