Mass of sodium + nitrogen +oxygen+ oxygen+ oxygen =

Mass of sodium + nitrogen +oxygen+ oxygen+ oxygen = =85 g/mol

Explanation:

Molar mass is the mass of 1 mole of the substance and its unit is g/mol

We find the molar mass by just adding atomic mass of the elements present in the chemical formula of the compound

For example  

Atomic mass of H is 1.008 (approximately 1)

Atomic mass of S is 32

Atomic mass of O is 16

There are 2, H atoms 1, S atom and 4, O atoms

So, the molar mass of the compound will be

The question says 1, Na  

1, N and  

3, O

So the chemical formula we get is

The molar mass of the compound is

=85 g/mol (Answer)
