How many molecules of water present in 0.20 moles of oxygen.

1.	How many molecules of water present in 0.20 moles of oxygen.
Answer» Hai! Molecular weight of H2SO4 = 98 G/mol 20 g of H2SO4 = 20 /98 ≈ 0.20 moles 1 mole = 6.023 × 10^23 molecules 0.20 moles =12.046 × 10^22 molecules One molecule of H2SO4 has 4 oxygen atoms, therefore ; Number of oxygen ATOM in 0.2 mole = 4 × 12.046 × 10^22 = 48.184 × 10^22 oxygen atoms i hope its help you
