Question

Calculate molarity of 9.8% (w/w) solution of H2SO4 if the density of the solution is 1.02g/l?

Answer 1

mark me brainliest answer plss

Molecular weight of H2SO4 is 98.079 g-
mol.
1 ml equals 1.84 g. Hence, 96 ml equals
96 x 1.84 = 176.64 g.
Therefore, 100 ml volume contains
176.64 g H2SO4. So 1 liter contains
1776.4 g.
Hence, the molarity is 1776.4/98.079 =
18.11 M.
