Answer:
The molecular weight of sodium sulfate is 142.1 g/mol. To calculate the mass of sodium sulfate, substitute the values in the formula. Therefore, the mass of sodium sulfate formed when we start with 200.0 grams of sodium hydroxide and you have excess sulphuric acid is 355.25g.
D: The atomic mass number
