Answer:
The number of mole of N in N2O is 0.00914mol
Explanation:
First, we calculate the molar mass of the compound N2O
N - 14.0067
O - 15.999
Mm of N2O = 2* 14.0067 + 15.999
= 44.0124g/mol
Then, we calculate the number of mole of N2O
Using this formula
n = number of mole
m = number of mass
Mm = molar mass
n = 0.201g/ 44.0124g/mol
= 0.00457mol
Since there are two moles of nitrogen in each mole of the compound N2O
= 0.00457mol * 2
= 0.00914mol of N
