Answer: Theoretical mass of sodium sulphate ( ) is 514.118 grams.
Explanation: For a given reaction,
As NaOH is used in excess, therefore it is an excess reagent and is a limiting reagent as the quantity of the product will depend on it.
We are given 355 grams of .
Molar mass of = 98.079 g/mol
Molar mass of = 142.04 g/mol
1 mole of is producing 1 mole of , so
98.079 g/mol of will produce 142.04 g/mol of
355 grams of will produce = of
Mass of = 514.118 grams
