Question

What mass of nitrous oxide can be formed from 48.7 g of nitrogen?
Express your answer to three significant figures and include the appropriate units.

Answer 1

$\\ \tt\bull\rightarrowtail2 N_2+O_2\longrightarrow 2N_2O$

• 2mol of N_2 forms 2mol of N_2O
• 1mol of N_2 forms 1mol of N_2O

Moles of N_2

$\\ \tt\bull\rightarrowtail \dfrac{48.7}{14}=3.4mol$

Molar mass of N_2O=44g/mol

Mass of N_2O formed

• 44(3.4)=132.16g
