What is the molarity of H2SO4 solution that has a density 1.84 gm/cc at 35℃ and contains solute 98?
18.4 M
18 M
4.18 M
8.14 M
Solution:
Molarity = (wt of solute / mol.wt) × (1000 / vol. of solution (in mL)) Volume of solution = mass / density = 100 / 1.84 = 54.34 mL Now molarity = (98 / 98) × (1000 / 54.34) = 18.4 M Hence, the correct option is 18.4 M
