Gce Model Questions Vol1 2023 Chemistry Question 1
Practice objective / multiple choice question 1 from the 2023 Gce Model Questions Vol1 Chemistry examination.
A gas collection over water apparatus is used to collect hydrogen gas produced from the reaction of an unknown metal M with excess hydrochloric acid. The graduated gas syringe shows a volume of \(125.0\) mL at \(298\) K and a total pressure of \(760\) mmHg. The water vapour pressure at \(298\) K is \(23.8\) mmHg. The metal is iron (atomic mass \(55.8\) g·mol⁻¹) and reacts according to \(\text{M} + 2\text{HCl} \rightarrow \text{MCl}_2 + \text{H}_2\). Calculate the mass of iron that reacted.
