\(1 \mathrm{~g}\) of a solute is added to \(18 \mathrm{~g}\) of water. In this aqueous solution, what is the mass per cent of the solute?
- A \(2 \%\)
- B \(5 \%\)
- C \(1 \%\)
- D \(10 \%\)
Answer & Solution
Correct Answer
(B) \(5 \%\)
Step-by-step Solution
Detailed explanation
Mass \(\%\) of solute \(=\frac{\text { Mass of solute }}{\text { Mass of solution }} \times 100\) Mass of solute \(=1 \mathrm{~g}\) Mass of solvent \(=18 \mathrm{~g}\) Mass of solution \(=1+18=19 \mathrm{~g}\) \(\therefore\) Mass \(\%\) of solute \(=\frac{1}{19} \times 100\)…
