Calculate the mass precentage of aspirin...

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

Text Solution

Verified by Experts

Mass of aspirin `(C_(9)H_(8)O_(4)) = 6.5 g`
Mass of acetonitrile `(CH_(3)CN) = 450 g`
Total mass of solution ` = 450+6.5`
` = 456.5 g`
Mass % aspirin ` = (6.5)/(456.5) xx 100`
` 1.424 %`
