What is the percent by weight of sodium in sodium sulfate (na2so4)? (the molar mass of na = 22.99, s = 32.07, and o = 16.00.) 16.18% 22.58% 32.37% 45.05% 51.17%

The percentage by weight of sodium in sodium sulfate is 32.37 %.

Explanation:

In , there are 2 sodium atoms, 1 sulfur atom and 4 oxygen atoms.

To calculate the mass percent of element in a given compound, we use the formula:

Mass of sodium =

Mass of sodium sulfate =

Putting values in above equation, we get:

Hence, the mass percent of sodium in sodium sulfate is 32.37%.
