Question

Calculate molality of 9.8(w/w) solution of h2so4 . Given the density of solution is 1.02g/ml

Answer 1

Answer:

,

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
