Question 9
Find The molality of 9.8% H2 S04 solution. Having density 2 g/mL is
(At. mass of s= 32u; O= 16 u; H=1u)​

Answer 1

Explanation:

9.8% (w/w) of H

2

SO

4

solution means 9.8 g of solute in 100 g of solution.

Density of H

2

SO

4

=1.2 g/ml

The volume of the solution =

Density

Mass

=

1.2

100

=83.33ml

Molarity =

98×83.33

9.8×1000

=1.2 M
