Question

the empirical formula of a compound is CH2o.it s molecular mass is 90.the molecular formula is:​

Answer 1

Answer:

molecular weight: If the molecular weight is 30, the molecular formula is CH2O If the molecular weight is 60, the molecular formula is C2H4O2 If the molecular weight is 90, the molecular formula is C3H6O3 etc.

Answer 2

Answer:

C3H6O3..

Explanation:

wkt M=90...

and Eperical formula weight is 30

so, n= M/EF weight

and n=3

....(EF) n=>(CH2O)3

molecular formula is C3H6O3
