Ascientist heated 10 grams of mercuric oxide and formed 9.3 grams of liquid mercury how many grams of oxygen were formed

0.74 grams of oxygen were formed.

Explanation:

To calculate the moles, we use the equation:

For mercuric oxide:

Putting values in above equation, we get:

According to stochiometry,

2 moles of gives 1 mole of

Thus 0.046 moles of gives= moles of

Mass of produced=
