Chapter 8 Practice: Mole-Mole Conversions

QuestionAnswer
4 Fe + 3 O2 --> 2 Fe2O3 How many moles of Fe2O3 are produced from 15 moles of Fe? 15 mol Fe x 2 mol Fe2O3/4 mol Fe = 7.5 mol Fe2O3
2 NH3 + H2SO4 --> (NH4)2SO4 How many moles of (NH4)2SO4 are produced from 30 moles of NH3? 30 mol NH3 x 1 mol (NH4)2SO4/2 mol NH3 = 15 mol (NH4)2SO4
2 Na + Cl2 --> 2NaCl How many moles of Cl2 are needed to react with 6.7 moles of Na? 6.7 mol na x 1 mol Cl2/2 mol Na = 3.35 mol Cl2
2 Na + Cl2 --> 2NaCl How many moles of NaCl are needed to produced by 3.2 moles of Cl2? 3.2 mol Cl2 x 2 mol NaCl/1 mol Cl2 = 6.4 mol NaCl
2 Na + Cl2 --> 2NaCl How many moles of Na are needed to react with 3.2 mol Cl2? 3.2 mol Cl2 x 2 mol Na/1 mol Cl2 = 6.4 mol Na
N2 + 3H2 --> 2NH3 How many moles of N2 are produced by 7.24 mol of NH3? 7.24 mol NH3 x 1 mol N2/2 mol NH3 = 3.62 mol N2
N2 + 3H2 --> 2NH3 How many moles of H2 are produced from 7.24 mol of NH3? 7.24 mol NH3 x 3 mol H2/2 mol NH3 = 10.86 = 10.9 mol H2
N2 + 3H2 --> 2NH3 How many moles of NH3 are produced by .6 mol of N2? .6 mol N2 x 2 mol NH3/1 mol N2 = 1.2 mol NH3

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
