Question

How many6 moles of nitrogen and in dinitrogen oxide?

Answer 1

The molar mass of nitrogen dioxide to the nearest gram-per-mole is 46 g/mol.

Nitrogen dioxide contains one nitrogen atom and two oxygen atoms.

Nitrogen's molar mass is 14.0067 g/mol.Oxygen's molar mass is 15.9994 g/mol(2)(15.9994 g/mol) = 31.9988 g/mol

The sum of these molar masses is:

14.0067 g/mol + 31.9988 g/mol = 46.0055 g/mol

This rounds to 46 g/mol.

hope you got it.
