1. Mass% of Na is 32.5%, Mass% of S is 22.5%, Mass% of O is 45%
2. Mass% of Na is 32.5%, Mass% of S is 45%, Mass% of O is 22.5%
3. Mass% of Na is 45%, Mass% of S is 22.5%, Mass% of O is 32.5%
4. Mass% of Na is 22.5%, Mass% of S is 32.5%, Mass% of O is 45%

We know that

Molecular weight of Na2SO4 = 23 x 2 + 32 + 16 x 4

= 46 + 32 + 64

= 142 g

The mass percentage can be found using the formula

Mass % = mass of elements present in the compound/ total mass of compound x 100

The mass of Na in this compound is 46 g

So Mass % of Na in this compound = 46 x 100/ 142 = 32.5%

Mass of sulphur in this compound = 32 g

So Mass % of sulphur in this compound = 32 x 100/ 142 = 22.5%

Mass of O in this compound = 64 g

So mass % of O in this compound = 64 x 100/ 142 = 45%

Therefore, the mass percent of different elements in sodium sulphate Na2SO4 is Mass% of Na is 32.5%, Mass% of S is 22.5%, and Mass% of O is 45%.

Summary:

## Calculate the mass percent of different elements in sodium sulphate Na2SO4.

The mass percent of different elements in sodium sulphate Na2SO4 is Mass% of Na is 32.5%, Mass% of S is 22.5%, Mass% of O is 45%.
