Atoms, molecules and stoichiometry — practice question

Two $1\,\text{g}$ portions of $Y$ are each allowed to react fully, one with sodium and the other with sodium carbonate. The gas volumes formed are then gathered and measured. The relative gas volumes are: with $\text{Na}$: $2$ with $\text{Na}_2\text{CO}_3$: $1$ What might $Y$ be?

  • A$\text{CH}_3\text{CH(OH)CH}_2\text{OH}$
  • B$\text{CH}_3\text{CH(OH)CO}_2\text{H}$
  • C$\text{CH}_3\text{COCH}_2\text{OH}$
  • D$\text{CH}_3\text{COCO}_2\text{H}$
