Answer 1

Mass percentage of

aspirin= Mass of aspirin×100/Mass of aspirin+Mass of acetonitrile

= 6.5/6.5+450×100

=1.424

Answer 2

Given:

Mass of:

Aspirin $\sf{(C_{9}H_{8}O_{4})}$ = 6.5 g

Acetonitrile $\sf{(CH_{3}CN)}$ = 450 g

Now:

Total mass of the solution:

$\implies$ 6.5 + 450

$\implies$ 456.5 g

Therefore:

Mass percentage of aspirin $\sf{(C_{9}H_{8}O_{4})}$:

$\implies$ $\frac{6.5}{456.5} \times 100$

$\implies$ $1.42$

Final answer: 1.42 %
