Question

Example 2.1 A solution contains 40 g of
common salt in 320 g of water.
Calculate the concentration in terms of
mass by mass percentage of the
solution.
2.2.3​

Answer 1

Explanation:

Mass of solute = 40g

Mass of solution= Mass of(solute+solvent)

=(40+320)g

Mass/Mass% = Mass of solute/Mass of solution×100

= 40/360 ×100

= 100/9

=11.11%
