Question

To separate a saturated solution of 30 gram of sodium chloride is dissolved in hundred gram of water at 293 degree Kelvin find concentration of salt at that temperature

Answer 1

Explanation:

Here, solute is NaCl(30 g)

& solvent is Water (100 g)

293k = 20°C which is room temperature

Therefore,

concentration of the solution is

= mass of solute ( NaCl) / mass of solvent (water) × 100

= 30 / 100 × 100

= 30 %
