The Data Booklet should be used for this question. $1.00\,\text{g}$ of a metallic element reacts completely with $300\,\text{cm}^3$ of oxygen at $298\,\text{K}$ and $1\,\text{atm}$ pressure to produce an oxide containing $\text{O}^{2-}$ ions. At this temperature and pressure, the volume occupied by one mole of gas is $24.0\,\text{dm}^3$. What could be the identity of the metal?
- Acalcium
- Bmagnesium
- Cpotassium
- Dsodium
