Question
The molarity of H2SO4 solution, which has a density 1.84g/cc. at 35oC and contains 98% by weight, is
Options
A.1.84 M
B.18.4 M
C.20.6 M
D.24.5 M
Solution
100 gm solution contains 98 gm H2SO4 
cc. contains 98 gm H2SO4
= 100c.c solution contains
× 1.84 × 1000 gm H2SO4
moles of H2SO4
= 18.4 M.
cc. contains 98 gm H2SO4 = 100c.c solution contains
× 1.84 × 1000 gm H2SO4 moles of H2SO4 = 18.4 M.
