The chemical equation below shows the burning of magnesium (mg) with oxygen (o2) to form magnesium oxide (mgo). 2mg + o2 2mgo the molar mass of o2 is 32.0 g/mol. what mass, in grams, of o2 is required to react completely with 4.00 mol of mg? a)2.00 b)64.0 c)128 d)256

B) Mass of O2 required = 64.0 g

Explanation:

Given:

Moles of Mg = 4.00 moles

To determine:

Mass of O2 that reacts completely with 4 moles of Mg

Explanation:

The given reaction is:

2Mg + O2 → 2MgO

Based on the reaction stoichiometry:

2 moles of Mg reacts with 1 mole of O2

Therefore, 4 moles of Mg will need:

Molar mass of O2 = 32 g/mol
