Question

A 10 % solution was made by dissolving h2so4 in 90ml of water. calculate the volume of h2so4 used

Answer 1

Answer:

Given,

Volume of H

2

SO

4

=10ml

Density of H

2

SO

4

=1.84g/ml

Now, we know,

Mass=Density×Volume

=(10ml×1.84g/ml)g

=18.4g

Total volume of the solution =(10+90)ml

=100ml

Mass by volume percentage=

Volumeofthesolution

Massofsolution

×100

=

100ml

18.4g×100

%

=18.4%

Hence, the mass by volume percentage of the solution is 18.4%
