Question

Calculate the molarity of sulphuric acid solution contains 98% by mass,with density is 1.84gcm^-1

Answer 1

Answer:

Given:

Density=1.98g

weight of H

2

SO

4

=98g

weight of solution=100g

∴volume of solution=

1.98

100

=50.5cm

3

weight of solvent(water)=100-98=2g

Molecular weight of H

2

SO

4

=98g/mol

∴ no of moles in 98g=
