Question

A compound is composed of atoms of only two elements, carbon and
oxygen. If the compound contain 53.1% carbon, what is its empirical
formula.

Answer 1

Answer:

n(C3H2)

Explanation:

Empirical formula : CnHn

compound weight :100g

weight of C : 53.1% = 53.1g

weight of O : 100-53.1= 46.9g

atm.Weight of C = 12

atm.Weight of O = 16

approx n of C = 53.1/12 = 4.425

approx n of C = 46.9/16 = 2.931

4.425 : 2.931 = 1.5 : 1 = 3 : 2

hence E F : n(C3H2)
