# 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.

Given,
Mass of solute (NaCl) $$= 36 g$$

Mass of solvent (H2O) $$= 100 g$$

Now, Mass of solution (NaCl + H2O) $$= 136 g$$

We know that, $$Concentration =$$ $$Mass \ of \ solute \over Mass \ of \ solution$$ $$× 100$$

=> $$Concentration =$$ $$36 \over 136$$ $$× 100 = 26.47%$$

Hence, the concentration of the solution is 26.47%
