How many moles of nitrogen are in 73.0g of nitrous oxide n2o

Answer : The number of moles of nitrogen present in nitrous oxide is 3.32 moles.

Explanation : Given,

Mass of nitrous oxide = 73.0 g

Molar mass of nitrous oxide = 44 g/mole

Now we have to calculate the moles of .

Formula used :

Now we have to calculate the moles of nitrogen in nitrous oxide.

In molecule, there are 2 moles of nitrogen atoms and 1 mole of oxygen atom.

As, 1 mole of contains 2 moles of nitrogen

So, 1.66 moles of contains moles of nitrogen.

Therefore, the number of moles of nitrogen present in nitrous oxide is 3.32 moles.
