PROBLEM 98P

How many grams of magnesium oxide form when 14.8 L of oxygen gas, measured at STP, completely reacts with magnesium metal according to this reaction?

2 Mg(s) + O2(g) → 2MgO(s)

Step-by-Step Solution:
Step 1 of 3

Solution 98P

Given:

Volume of oxygen = 14.8 L

2 Mg(s) + O2(g) → 2MgO(s)

We will have to find out the mass of MgO formed in the given reaction.

At STP (standard temp and pressure, 0 deg C and 1 atm) 1 mole of any ideal gas occupies a volume of 22.4 L

So moles O2 = volume (L) / 22.4 L/mol

= 14.8 L / 22.4 L mol-1

= 0.6607 mol O2

The balanced equation shows that 1 mole O2 forms with 2 moles MgO

So moles MgO = 2 moles O2

=2 0.6607 = 1.3214

mass = molar mass moles

= 40.3 g/mol 1.3214 mol

= 53.25 g

Thus the mass of MgO is 53.25 g.
