|
Answer» ulate the mass of the individual elements present in SODIUM sulphate , ONE mole of sodium sulphate is taken. Sodium sulphate contains two moles of sodium, one mole of sulphur, and 4 moles of oxygen. The mass percentage of the elements are as follows Molecular weight of sodium sulphate = 142 grams 2 moles of sodium (Na) = 2 X 23 grams = 46 grams One mole of sulphur (S) = 32 grams 4 moles of oxygen (O) = 4 x 16 grams = 64 grams Mass Percentage, Sodium = = 32.39% Sulphur = = 22.53% Oxygen = = 45.06% |
