How many grams are contained in 3.22 moles of dinitrogen tetroxide?
Molar mass of
Mass of 3.22 moles of
The formula for dinitrogen tetroxide is
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.
