Question

a compound has 20% of carbon and the rest is hydrogen. if the amount of hydrogen in the compund is 160g then find the amount of carbon and total amount of the compound
​

Answer 1

Let the mass of hydrocarbon be 100g

Therefore , H=20g=20 moles

C=80g= 80/12 moles=6.67moles

C:H=6.67:20=1:3

Therefore, the empirical formula of hydrocarbon is CH3
