2Mg + O2 ==> 2MgO
mols Mg = grams/atomic mass = ?
Using the coefficients in the balanced equation, convert mols Mg to mols MgO. In this case that is mols Mg x 1 = mols MgO
Then convert mols MgO to grams.
g MgO = mols MgO x molar mass MgO = ?
If 10g of magnesium reacted with 5g of oxygen how much magnesium oxide would you produce? How do you know?
