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

Explanation:

Mass of solute (sodium chloride) =36g

Mass of solvent (water) =100g

Mass of solution = Mass of Solute + Mass of solvent

= 36g +100g = 136g

concentration = mass of solute / mass of solvent × 100

so , concentration = 36grm/136grm ×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%
