If the balanced equation reads:

2N2 + O2 ———> 2N2O

You should have 1.72 moles of N2.

Answer:

Moles of N = 3.45

Explanation:

Given:

Mass of N2O = 76.0 g

To determine:

Moles of N present in the given mass of N2O

Explanation:

Based on the formula stoichiometry:

1 mole of N2O contains 2 moles of N

Now, 1 mole of N2O = 44.0 g (i.e. the molar mass of N2O)

44.0 g of N2O contains 2 moles of N

Therefore, moles of N in 76.0 g of N2O would be:

= [tex]= \frac{76.0 g \ N2O *2\ moles\ N}{44.0g\ N2O} =3.45\ moles[/tex]
