    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
