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`.

Explanation

`"Mass percent(Mass %)"=("Mass of solute")/("Mass of solution")xx100`
Mass of aspirin = 6.5 g , Mass of acetonitrile=450 g
`"Mass percent of aspirin"=((6.5g))/((6.5g+450g))xx100=1.424%`
