  1. How many atoms of C are in an aspirin (C9H8O4) pill that contains 0.2000 grams of aspirin?

  2. mole-to-mole ratios Silver nitrate is reacted with barium chloride: How many grams of barium chloride are needed to make 2.24 grams of solid?

  3. mole-to-mole ratios Chromium (III) chlorate is reacted with sodium oxide: a) What is the balanced chemical equation? b) How many grams of sodium oxide are needed to react with 15.67 grams of chromium (III) chlorate

  4. mole-to-mole ratios Chromium (III) chlorate is reacted with sodium oxide:

  5. You burn 2769. grams of an unknown hydrocarbon and collect 8505 grams of CO2(g) and 3918 grams of H2O(g). • What is the empirical formula of the hydrocarbon? • If the molar mass of the hydrocarbon is 114.26 g/mol, what is the molecular formula?

  6. You burn 2769. grams of an unknown hydrocarbon and collect 8505 grams of CO2(g) and 3918 grams of H2O(g).

  7. You burn 2769. grams of an unknown hydrocarbon and collect 8505 grams of CO2(g) and 3918 grams of H2O(g). b) If the molar mass of the hydrocarbon is 114.26 g/mol, what is the molecular formula?

  8. Mole – Mole revisited What mass of liquid will be produced from the reaction of bismuth (V) hydroxide with 3.28 moles of sulfuric acid? 2 Bi(OH)5(s) + 5 H2SO4(aq) Bi2(SO4)5(aq) + 10 H2O(l)

  9. mole-to-mole ratios What mass of liquid will be produced from the reaction of 203 g of bismuth (V) hydroxide with a sulfuric acid solution? 2 Bi(OH)5(s) + 5 H2SO4(aq) Bi2(SO4)5(aq) + 10 H2O(l)

  10. mole-to-mole ratios 2 Bi(OH)5(s) + 5 H2SO4(aq) Bi2(SO4)5(aq) + 10 H2O(l) Start with 3.28 mol H2SO4(aq) Start with 203 grams of Bi(OH)5 What if we start with 3.28 mol H2SO4(aq) AND 203 grams of Bi(OH)5?

  11. ACME Tricycle Company Tricycles are made of 1 frame, 2 pedals, and 3 wheels A shipment comes in consisting of 1387 f, 2744 p, 4188 w. How many tricycles can be built?

  12. ACME Tricycle Company The smallest amount of product is how much can actually be made! (only 1372 tricycles can be made in this case) The starting material that you run out of is the __________ ___________(pedals in this case) The starting material that you have left over is the ________ ____________(frames and wheels in this case)
