Question

How many grams are in 2.00 moles of sodium sulfate

Answer 1

a) 284 grams Na₂SO₄

Procedure

To solve this problem you will need to determine the formula for sodium sulfate using nomenclature rules or search for the molecule name in a book or guide

Sodium sulfate formula is Na₂SO₄

Then determine the molecular weight

Sodium sulfate molecular weight is 142.04 g/mol

Determine the grams as following

`2\text{ mole Na}_2\text{SO}_4\frac{142.04\text{ g}}{1\text{ mole}}=284.08\text{ grams Na}_2\text{SO}_4`
