Question

A solution contains 35 gm of common salt in 300 gm of water . Calculate the concentration of the solution.

Answer 1

clearly ,
mass of salt =35 g
mass of water=300g
total mass= 300+35
=335g
hence concentration of solution is
35/335×100
10.44%

Answer 2

Explanation:

formula = (mass%)= mass of solute / mass of solution ×100

mass%= 35/(35+300)×100

= 35 / 335 × 100

= 10.45%

so the mass % is 10.45%
