Can someone PLEASE help me with this problem, I’ve tried it multiple times and keep getting it wrong :(

Explanation:

Okay.

From convervation of mass in chemical processes, all the reactants combined have the same mass as all the products.

m react = m prod

m Hg + m O 2 = m HgO + m O 2

114.0g+12.8g=123.1g+ m O 2

Solving for mO2 = 3.70 g

This is what I know.

I do hope I helped you! :)
