Question

The correct molecular formula of a compound that has an empirical formula c2 h2o and molecular weight of 168 is

Answer 1

molecular formula of compound is c8h8o4

because molecular weight is 168 the

n=molecular weight/empirical mass

n=168/42=4

then c2h2o×4=c8h8o4

Answer 2

Answer:

C8 H8 O4

Explanation:

this is because empirical formula of compound is 42

so 168 divided by 42 gives 4

so molecular formula is 4 times the empirical formula

4 (C2 H2 O ) = C8 H8 O4
