mole-mole calculations

6H2O(l) + 6CO2(g) ? C6H12O6(s) + 6O2(g)

If 8.00 moles of water react with carbon dioxide, how many moles of glucose are produced?

If 6.00 moles of oxygen were produced, how many moles of carbon dioxide were needed to react?

Always use mole-mole ratio somewhere in these problems!!

mole-mass / mass-mole calculations

6H2O(l) + 6CO2(g) ? C6H12O6(s) + 6O2(g)

What mass, in grams, of carbon dioxide is needed to react with 3.00 mol of water in this reaction?

2Mg(s) + O2(g) ? 2MgO(s)
What mass (g) of magnesium oxide is produced from 2.00 mol of magnesium?

C(s) + SO2(g) ? CS2(l) + CO(g) (unbalanced)
5C(s) + 2SO2(g) ? CS2(l) + 4CO(g) (balanced)
If 8.00g of SO2 reacts, how many moles of each product are formed?

mass/mass calculations

5C(s) + 2SO2(g) ? CS2(l) + 4CO(g)

How many grams of carbon monoxide are produced from the reaction of 16.0 g of SO2
with carbon?
