Answer:
65 g of nitrous oxide contain 2.96 moles of nitrogen.
Explanation:
Given data:
mass of N₂O = 65 g
moles of nitrogen = ?
Solution:
First of all we will calculate the moles of N₂O.
number of moles = mass / molar mass
number of moles = 65 g/ 44.01 g/mol
number of moles = 1.48 mol
One mole of nitrous oxide contain two mole of nitrogen.
we will multiply the moles of nitrous oxide with two.
1.48 mol × 2 = 2.96 moles
So 65 g of nitrous oxide contain 2.96 moles of nitrogen.
