2. Give the empirical, molecular and structural formulae for hydrogen peroxide. Hint - these are given in your textbook (use the index). (1.5 marks) 3. Give the molecular formula and the structural formula for acetic acid (also in your textbook). (1 mark) Continued on next page B-6 EXPERIMENT B: STOICHIOMETRY AND REACTIONS IN AQUEOUS SOLUTIONS PRELAB ASSIGNMENT (CONTINUED) 4. (a) In a combustion reaction all of a sample of octane was consumed to form carbon dioxide C8H18 (1)→ CO₂ (g) Give the mole ratio of CsH₁s (1) to CO₂ (g) in that reaction. (0.5 mark) (b) All of a sample of Mg3N2 (s) was converted to Mg(OH)2 (s) by Mg3N₂ (s) → Mg(OH)2 (s) Give the mole ratio of Mg(OH); (s) to Mg,N₂ (s) in that reaction. (0.5 mark) 5. Suppose you analyze a sample of fertilizer by the procedure of this experiment and obtain 1.000g of MgNH₂PO4 6H₂O (s) as the product. Then (a) Calculate the molar mass of MgNH₂PO4-6H₂O (s). (1 mark) (b) Calculate the molar mass of P:Os. (0.5 mark) (c) Calculate the equivalent mass of "P-O," initially in the sample. (1 mark) 6. A mole is a unit like a dozen. Use 1 mol -6.02214 x 102 to calculate the number of dogs in 3.32 x 10-24 mol of dogs. (0.5 mark) 2. Give the empirical, molecular and structural formulae for hydrogen peroxide.
