Neco 2018 Chemistry Question 6
Practice objective / multiple choice question 6 from the 2018 Neco Chemistry examination.
A 2.00 g sample of an unknown metal oxide MO is reacted with excess hydrogen gas at 298 K and 1 atm. The reaction is \(\text{MO} + \text{H}_2 \rightarrow \text{M} + \text{H}_2\text{O}\). The volume of water vapour produced is measured to be 0.560 L. Given that the atomic mass of oxygen is 16.0 g·mol\(^{-1}\), determine the atomic mass of the metal M (in g·mol\(^{-1}\)).
