# How many grams are contained in 3.22 moles of dinitrogen tetroxide?

##### 2 Answers

Molar mass of

Mass of 3.22 moles of

The formula for dinitrogen tetroxide is

Assume that:

n - number of moles

m - mass of substance

M - molar mass

3.22 moles (n) of

Next step is to find out the molar mass (M). Before that, break up the formula, first, to make sure that you know what atoms are present. You can see that Nitrogen and Oxygen are present. If you refer to your periodic table, the molar mass of Nitrogen is 14.0 g/mol and Oxygen 16.0 g/mol.

Therefore, the molar mass (M) of dinitrogen tetroxide is:

Your last step is to find out the mass.

Look back at the

The mass of

[m = 92.0 g/mol

Note that this answer is rounded to 3 significant figures.

Overall, 296.2 grams are contained in 3.22 moles of dinitrogen tetroxide.
