Question

the empirical formule of compound is c2h4o if its molecular mass is 88 g mol-1than its molecular formula is

Answer 1

Explanation:

empirical weight =2(12)+4(1)+16=44g

molecular mass=88g

n=molecular mass/empirical weight

n=88/44

n=2

molecular formula=n × empirical formula

molecular formula =2(c2h4o)

molecular formula is c4h8o2
