Question

Calculate molecular formula and empirical formula of compound containing C=54.3%,
H-9%, 0-36.7% molecular mass of compound is 88.
​

Answer 1

${\mathbb{\huge{\Blue{HEY}}}}$

C=54(approx)

C=54/12=4.5

H=9

0=36%(approx)

O=3

emperical formula=C2H3O

MFM=88

EFM=44(approx)

n=2

Molecular formula=C4H6O2
