Question

the empirical formula of an organic compound is CHO. if the molecular mass is 87 what will be the molecular formula​

Answer 1

Explanation:

empirical mass of CHO is 12+1+16=29

let the organic compound of mass 89 be CxHxOx= x(12+1+16) =89

x=3

molecular formula =C3H3O3

Answer 2

Answer:

weight of empirical formula=12+1+16=29

molecular formula=n×empirical formula

n=molecular formula/empirical formula

n=87/29=3......

therefore, molecular formula C3H3O3
