### Decomposition of Mercury(II) Oxide (HgO)

The compound HgO can be decomposed to form Hg and O₂. This can be represented at the atomic level by the chemical equation:

\[ 2HgO \rightarrow 2Hg + O_2 \]

According to the law of conservation of mass, if 26.4 grams of HgO decomposes and 24.4 grams of Hg is formed, how many grams of O₂ must simultaneously be formed? 

\[ \boxed{\phantom{answer}} \text{ grams O}_2 \]
