Balance the equation first.
Then, change the 22.4 g O2 to moles.
Look at the coefficents in the balanced equation. That tells you how much mass of mercury(II)oxide is needed. I will be happy to critique your work, if needed.
How do I solve this problem?
According to the following reaction, how many grams of mercury(II) oxide are
needed to form 22.4 grams of oxygen gas?
mercury(II) oxide (s) mercury (l) + oxygen (g)grams mercury(II) oxide
