How many moles of n are in 0.185 g of n2o?

pickupchik [31]

The mass of $N_{2}O$ is 0.185 g.

To calculate the number of moles first calculate the molar mass of $N_{2}O$ .

$M_{N_{2}O}=2\times M_{N}+M_{O}$

Molar mass of nitrogen and oxygen is 14 g/mol and 16 g/mol respectively

Thus, $M_{N_{2}O}=2\times 14 g/mol+18 g/mol=44 g/mol$

Now, number of moles can be calculated from mass and molar mass as follows:

$n=\frac{m}{M}=\frac{0.185 g}{44 g/mol}=0.0042 mol$

Therefore, number of moles of 0.185 g $N_{2}O$ is 0.0042 mol.
