How many moles of oxygen is required to produce 2.8 moles of water?

2.8 moles

Explanation:

The formula for water is H2O, so one mole of water contains two moles of hydrogen and one mole of oxygen.

Here, the ratio of water particles to oxygen particles is one to one.

Therefore, in 2.8 moles of water, there are 2.8 moles of oxygen.

Hence, 2.8 moles of oxygen are required to produce 2.8 moles of water.
