Determine the number if moles of MgO that form from the reaction of 4.4 moles of O2 in the following unbalanced reaction:
Mg + O2 ----> MgO

The balanced equation is:
2Mg + O2 -----> 2MgO

a. 1.1 moles
b. 4.4 moles
c. 17.6 moles
d. 2.2 moles
e. 8.8 moles

If I did this right I get 8.8 moles, is that correct or I am still doing this wrong? Please Help me!

• Chemistry -

you are correct. You get twice the moles of product as you had of O2
