Question:

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

Answer:

Mass of sodium chloride = 36g

Mass of solvent (water) = 100g

We know that,

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

= 136 g
