Answer:

$n_N=7.41x10^{-3}molN$

Explanation:

Hello,

In this case, one develops the following mass-mole relationship, taking into account that $N_2O$ has two nitrogens inside, thus:

$n_N=0.163gN_2O*\frac{1molN_2O}{44gN_2O}*\frac{2molN}{1molN_2O}\\n_N=7.41x10^{-3}molN$

Best regards.

First convert 0.163 grams of N2O to mol by dividing it with the molecular weight. The molecular weight of N2O is 44 grams/mol. The answer would be 3,79x10^-3. Then multiply it with 2 since there are 2 Nitrogen in one mole of N2O. Therefore, there are 7.41x10^-3 moles of Nitrogen.
