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.
