Calculate the mass percentage of aspirin...

Calculate the mass percentage of aspirin `(C_9H_8O_4)` in acetonitrile `(CH_3CN)` when 6.5 g of `C_9H_5O_4` is dissolved in 450 g of `CH_3CN` .

Text Solution

Verified by Experts

Mass per cent of aspirin = (Mass of aspirin)/(Mass of aspirin + Mass of acetonitrile) x 100
` = (6.5)/(6.5 + 450) xx 100 = 1.424%`
