Question

Concentrated aqueous sulphuric acid is 98% H2SO4 (w/v) and has a density of 1.80 g/mL . Molarity of solution is

Answer 1

as we know the formula for concentration :-

c(H2SO4)= n(H2SO4)/v(solution)

m(H2SO4)/M(H2SO4) x V (solution)

m(solution) x w(H2SO4)/M(H2SO4) x V (solution)

V(solution) x d(solution) x w(H2S04)/M(H2SO4) x V(solution)

d(solution) x w(H2SO4)/M(H2SO4)

c(H2SO4)=1800 g/L x 0.98/ 98 g/mol=18mol/L =18M

hope it helps..
