Question

How many moles of N are in 0.209 grams of N20

Answer 1

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

Step-by-step explanation:

Given data:

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 .
