Question

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

Answer 1

Answer:

Mass of solute =36g

Mass of solvent =100g

Mass of solution =Mass of solute +Mass of solvent = 100g +36g =136g

Concentration = Mass of solute / Mass of solution *100

=36/136 *100

=26.47%

Answer 2

$\huge\blue{\fbox{\fbox{\pink{\mathcal{ANSWER}}}}}$

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%
