    a) 64.06 g SO2 x (1 mole / 64.06 g) = 1 mole SO2

    b) 1 mole water = 1 mole H2O

    c) 88.02 g CO2 x (1 mole / 44.01g) = 2 moles CO2

    d) 2.02 g H2 x (1 mole / 2.02 g) = 1 mole H2

    so you have 1 mole SO2, 1 mole H2O, 1 mole H2 and 2 moles CO2.

    since each 1 mole contains 6.022x10^23 molecules..... you tell me the answer.
