Question

Define a solution. If 20 ml of H2SO4 are dissolved in 90 ml of water, calculate the concentration

Answer 1

18.4%

Given,

Volume of H2SO4=10ml

Density of H2SO4=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=VolumeofthesolutionMassofsolution×100

=100ml18.4g×100%

=18.4%

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

Answer 2

18.4%

Given,

Volume of H2SO4=10ml

Density of H2SO4=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=VolumeofthesolutionMassofsolution×100

=100ml18.4g×100%

=18.4%

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