What mass of N2 will be needed to produce 31.5 grams of N2O5?
SCORPION-xisa [38]

Answer: d) 16.34 grams

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}  

\text{Moles of} N_2O_5=\frac{31.5g}{108.01g/mol}=0.292moles

4N_2+5O_2\rightarrow 2N_2O_5  

According to stoichiometry :

As 2 moles of N_2O_5 are produced by= 4 moles of N_2

Thus 0.292 moles of N_2O_5 are produced by=  =\frac{4}{2}\times 0.292=0.584moles of N_2

Mass of N_2=moles\times {\text {Molar mass}}=0.584moles\times 28g/mol=16.34g

Thus 16.34 g of N_2 will be needed
