Find the molarity and molality of a 15% solution of H2SO4 ( density=1.020 g/cm3 and atomic mass = H=1, O=16, S=32amu)

Dear Student,

Molarity can be calculated as:

where %mass = 15 %

d = 1.020 g/cm3

MM = 98 g/mol

Now, Molality can be calculated with the help of Molarity, using the following formula:

where, M= molarity = 1.56 M

d = density = 1.020 g/cm3

MM = Molar mass of solute = 98 g/mol

Hope, its clear now.

Enjoy learning!!
