Calculate the mass percentage of aspirin `(C_(9)H_(8)O_(4))` in acetonitrile `(CH_(3)CN)` when 6.5 g of `C_(9)H_(8)O_(4)` is dissolved in 450 g of `CH_(3)CN`.

Text Solution

Verified by Experts

The correct Answer is:

`1.424%`

Mass percentage of aspirin
`=(Mass of asp iri ng xx100)/(Mass of asp i r i n+Mass of CHM_(3)CN)`
`=(6.5)/(6.5+450)xx100`
