A2 Chemistry example of how to find the empirical formula from combustion data

HideShow resource information

An organic coumpound X has contains C,H,N and O. 0.132g of X is burnt to form 0.072g of water , 0.176g of CO2 and 24cm3 of Nitrogen

1. Work out the moles of each of the given elements

24/24000= 0.001 mole of N  moles * rmm = grams 0.001* 28 = 0.028g

2/18 * 0.072 = 0.008 grams of H- so 0.008 moles of H

12/44 * 0.176= 0.048 grams of C moles of C =…
