Masses Involved<br />
• What will be the mass of 6 mol of H 2 ?<br />
• 6 mol (2.0g/mol) = 12g H 2<br />
• According to our picture, for every 4g of<br />
H 2 , 32g of O 2 are required. We need 3<br />
times as much oxygen: 3 x 32g = 96g O 2<br />
needed.<br />
• The original reaction made 36g of water, so<br />
starting with 6g of hydrogen makes 108g<br />
H 2 O (3 times as much.)
