Question

A compound containing 28g of nitrogen combined with 80g oxygen. Find its empirical formula

Answer 1

Answer:

N2O5

Explanation:

1. Divide the given mass of elements with their Molar mass

N= 28/14 = 2 & O= 80/16 = 5

2. Take simplest ratio from the division and examine combinations

Thus we get 2:5 i.e., N2O5

Therefore the empirical formula is N2O5
