A compound on analysis gives the following percentage composition: K=31.83, Cl=28.98 and O=39.19. find the molecular formula of the compound if its molecularr mass be 122.5.

Text Solution

Verified by Experts


`therefore`Empirical formula of the compound`=KClO_(3)`, molecular formula=`(KClO_(3))_(n)`
`therefore`Molecular mass`=nxx(39+35.5+48)=122.5xxn`
`therefore 122.5xxn=122.5 or, n=1`
So, molecular formula off the compound `=KClO_(3)`.
