- Mass% of Na is 32.5%, Mass% of S is 22.5%, Mass% of O is 45%
- Mass% of Na is 32.5%, Mass% of S is 45%, Mass% of O is 22.5%
- Mass% of Na is 45%, Mass% of S is 22.5%, Mass% of O is 32.5%
- 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%.
