What mass of N2 will be needed to produce 31.5 grams of N2O5? 4N2 + 502 --> 2N2O5
a) 158.3 grams
b) 38.64 grams
c) 4.96 grams
d) 16.34 grams

d) 16.34 grams

Explanation:

To calculate the moles :

According to stoichiometry :

As 2 moles of are produced by= 4 moles of

Thus 0.292 moles of are produced by=  = of

Mass of

Thus 16.34 g of will be needed
