Calculate the mass percentage of aspirin...

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

Text Solution

Verified by Experts

`"Mass percent of aspirin "=("Mass of aspirin")/("Mass of aspirin "+"Mass of acetonitrile")xx100=(6.5)/(6.5xx450)xx100=1.424%.`
