Question

calculate (1)molarity and (2)molality of 4.9% (w/v) H²SO⁴ solution of density 1.12gcm-³​

Answer 1

Explanations

ANSWER

98% by weight of solution means 98g of H

2

SO

4

is present in 100g of solution.

Volume of solution =

density of solution

mass of solution

=

(1.8×1000)g/L

100g

Volume of solution =

18

w/v of solution = molarity =

volume of solution (in L)

number of moles of H

2

SO

4

Molarity =

volume of solution

given mass of H

2

SO

4

/ molar mass of H
