Question

find the empirical formula for oxide that contains 42.05g of Nitrogen and 95.95g of oxygen​

Answer 1

Answer:

weight of nitrogen =42.05g

• moles=3.004

weight of oxygen =95.95

• moles=5.996

• simplest ratio,

• of O 5.996/3.04=1.99=2(approx)

• of N 5.5996/5.996=1

therefore, empirical formula is NO2
