How many moles of N are in 0.209 grams of N20

There are 0.01 moles of N in 0.209 g of N₂O.

Explanation:

Given dа ta:

Mass of N₂O = 0.209 g

Moles of N = ?

Solution:

Number of moles of N₂O = Mass / molar mass

Number of moles of N₂O = 0.209 g / 44 g/mol

Number of moles of N₂O = 0.005 mol

Since one N₂O have two N atom because it is diatomic.

0.005 mol * 2 = 0.01 mol

There are 0.01 moles of N in 0.209 g of N₂O.
