How many molecules are there in the following 25.0 g H2SO4

1.536*10^23

Explanation:

One mole of any compound has N molecules.

Where N is the Avogadro's number

Molecular weight of H2SO4 is

H2 = 2

SO4 = 96

H2SO4 = 2+96

98g/mol

Hence the number of mole of H2SO4 in 25g = 25/98 = 0.2551mol

Number of molecules = 25/98 * 6.022*10^23

= 1.536*10^23 molecules
