Question

To make a saturated solution, 67 g of sodium chloride is dissolved in 120 g of water at 293 K. Find its concentration at this temperature.

Answer 1

Answer:

55.83%

Explanation:

Given :

• Mass of solute (sodium chloride) = 67 g

• Mass of solvent (water) = 120 g

To Find :

• Concentration at 293K

Solution :

Mass of solution = Mass of solute + Mass of solvent

= (67 + 120) g

= 187 g

Therefore, concentration (mass by mass percentage) of the solution.

$\sf{}\dfrac{Mass\ of\ the\ solute}{Mass\ of\ the\ solvent}\times100 \%$

$\sf{}\dfrac{67}{120}\times100 \%$

$\sf{}55.83\%$

Therefore,concentration of the solution is equal to 55.83%
