How do you calculate 1m h2so4?

Use the equation

Moles(m) = mass(g) / Mr (Relative Molecular Mass).

To calculate the Mr , refer to the Periodic Table, for Atomic Masses.

For H2SO4

We have

H x 2 = 1 x 2 = 2 ( 1 is the Atomic Mass of H )

S x 1 = 32 x 1 = 32 ( 32 is the atomic mass of S).

O x 4 = 16 x 4 = 64 (16 is the atomic mass of O).

Adding

2 + 32 + 64 = 98 the Mr of H2SO4

Substituting into the eq'n above

1 mole = mass(g) / 98

Algebraic rearrangement

mass(g) = 1 mole X 98(Mr)

mass(g) = 98 grams. is the mass of 1 mole of H2SO4 .
