Looking Back • If we go back to our first example: 1 1 1 1 16 16 1 1 1 1 16 16 • What if there were 6 H 2 molecules (or moles) rather than 2? How many O 2 molecules (or moles) would be required, and how many water molecules (or moles) could we make?
Mole Ratio • Three times as much hydrogen requires 3 times as much oxygen. 3 molecules or moles of oxygen are required. • Also 3 times as much water will be produced. 6 molecules or moles of water. • 6 H 2 + 3 O 2 6 H 2 O • Notice that the mole ratio (2:1:2) from the balanced equation has been maintained.
