How many moles of nitrogen, n, are in 82.0 g of nitrous oxide, n2o?

Answer : The number of moles of nitrogen present in nitrous oxide are 3.72 moles.

Explanation : Given,

Mass of  = 82.0 g

Molar mass of = 44 g/mole

First we have to calculate the moles of .

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

In nitrous oxide , there are 2 moles of nitrogen and 1 mole of oxygen.

As, 1 moles of contains 2 moles of nitrogen

So, 1.86 moles of contains of nitrogen

Therefore, the number of moles of nitrogen present in nitrous oxide are 3.72 moles.
