Equation 2Mg+O2= 2MgO

Lab data:
Magnesium ribbon= .04 grams
Magnesium Oxide= .09

2. Using the initial mass of magnesium, calculate the moles of oxygen and then moles of magnesium oxide produced. What is the mole ratio of the reactants?

3. Calculate the mass of magnesium oxide from the initial mass of magnesium.

4. Calculate the percent error, using the calculated mass of magnesium oxide and the actual mass of magnesium oxide produced in the experiment.
