Question

What will be the mass percentage aspirin C9H8O4 in acetonitrile CH3CN when 6.5g of C9H8O4 is dissolved in 450g of CH3CN

Answer 1

Answer:

Therefore, mass percentage aspirin in acetonitrile solution is 1.424 %

Explanation:

Mass percentage of aspirin in acetonitrile is -

% w/w = W(C₉H₈O₄)/[W(C₉H₈O₄)+W(CH₃CN)] × 100

% w/w = 6.5/(6.5+450) × 100

% w/w = 1.424 %

Therefore, mass percentage aspirin in acetonitrile solution is 1.424 %.
