- A \(0.5 \mathrm{~m}\)
- B ) \(0.1 \mathrm{~m}\)
- C \(1 \mathrm{~m}\)
- D \(0.05 \mathrm{~m}\)
Answer & Solution
Correct Answer
(C) \(1 \mathrm{~m}\)
Step-by-step Solution
Detailed explanation
Given, mass of \(\mathrm{HCI}=18.25 \mathrm{~g}\) Molar mass of \(\mathrm{HCI}=36.5 \mathrm{~g} / \mathrm{moI}\) Mass of water \(=500 \mathrm{~g}=0.5 \mathrm{~kg}\) Number of moles of \(\mathrm{HCI}=\) Mass of \(\mathrm{HCl} /\) Molar mass of…
