Question

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

Answer 1

Mass of solute (sodium chloride)=36 g(Given)
Mass of solvent (water)=100 g (Given)
Then, mass of sodium = Mass of solute + Mass of solvent
=(36+100 )g
=136 g
`=("Mass of Solute")/("Mass of Solvent")xx100%`
`=(36)/(136)xx100%`
=26.47%
