  1. Stoichiometry Race

  2. Rules • You can only work with your partner • All your work must be shown on the white board • First team gets 3 points • Second team gets 2 points • Third team gets 1 point Team with the highest score gets bubble gum!

  3. Molar Mass Determine the molar mass for the following: CH3

  4. Molar Mass Determine the molar mass for the following: Pb(NO3)2

  5. Molar Mass Calculate the number of moles of 26.2 g of gold.

  6. Molar Mass Calculate the number of moles of 41.5 g of calcium.

  7. Mass-Moles • Calculate the mass of 3 moles of Fe?

  8. Moles-Mass • Calculate the number of grams of 7.5mol of Pb.

  9. Moles-Volume • What is the volume of 3 moles of Cl2?

  10. Volume-Moles • How many moles of 42L of CH4?

  11. Moles-Particles • How many molecules are in 5.3 moles of H2C2O4?

  12. Particles-Moles • How many moles is 7.8x1023 atoms of Cu?

  13. Percent Composition • Calculate the percent composition of copper in CuBr2

  14. Question 8 • Calculate the percent composition of carbon in C6H10O6

  15. Empirical Formula • Determine the empirical formula of a compound that has the following percent compositions: Na 83.12%, N 16.88%

  16. Empirical Fromula • Determine the empirical formula of a compound that has the following percent compositions: 65.02 % Pt, 2.02% H, 9.34% N, 23.63% Cl.

  17. Gram-gram Stoichiometry • How many grams CHCl3 is will be produced from 50.0 g CH4? CH4 + 3 Cl2 CHCl3 + 3 HCl • What will the percent yield be if the actual yield is 400g?

  18. Gram-gram stoichiometry • What mass in grams of sodium carbonate, Na2CO3 is produced if 50.0 g of sodium oxide, Na2O, are reacted with excess carbon monoxide, CO, according to the fol­lowing chemical equation? 2Na2O(s) + CO(g) Na2CO3(s) + 2 Na(s)

  19. Limiting reactant • The reaction between solid sodium and iron III oxide is one in a series of reactions that inflates an automobile airbag. Na + Fe2O3→ Na2O + Fe • If 100.0 g Na and 100 g of Fe2O3are used in this reaction determine the limiting reactant and the mass of iron produced.
