Question

4.9g ofH2SO4 were discovered in 250 ml of solution calculate Molarity of
the solution

Answer 1

molarity=molar mass/volume

=4.9/0.25

=19.6g/l

Answer 2

here,
        the molar mass of H2SO4=4.9gm
        amount of solution(in ltr)=250/1000=0.25 ltr
molarity of the solution=no. of moles/ltr solution=4.9/0.25=19.6gm/ltr
