Calculate the mass percentage of aspirin...

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 :

Text Solution

Verified by Experts

6.5 g of `C_(9)H_(8)O_(4)` is dissolved in 450 g of `CH_(3)CN`.
Then, total mass of the solution
`= (6.5+45)g`
= 456.5 g
Therefore, mass percentage of `C_(9)H_(8)O_(4)`
`=(6.5)/(456.5)xx100`
`= 1.424 %`.
