Question

Calculate the mass of sulphuric acid having the density 20g /ml. The mass of H2SO4 is 49 percent​

Answer 1

Answer:

1.98g= Specific gravit

        1000ml×1.98=1980gram

Solution weight-Water weight of solutions

1980-510=1480 H2SO4

Numbers of moles of H2SO4=Mass of H2So4/Molar mass of H2SO4

                     =981480=15.10mol

Molality(m)=No of moles/mars of solution

                  51015.10=0.029moles
