CHEM403 Lecture Notes - Lecture 6: Molar Volume, Magnesium, Zinc Sulfide
Document Summary
Lab 6: investigating the molar volume of a gas. Temperature: mg (s) + 2hcl (aq) mgcl2 (aq) + h2 (g) Trial 1: (. 0777 atm)(1. 65794 l)/(. 08206)(294. 17083 k)=5. 32 x 10^-4 mol h2. Trial 2: (. 0715 atm)(1. 65861 l)/(. 08206)(294. 59178 k)= 4. 9 x 10^-4 mol h2. 0149g of mg x (1 mol mg/24. 31 g) / (1 mol h2/1 mol mg) = 5. 76 x 10^ -4 mol h2 (we only have one theoretical yeild because we used . 014g of magnesium for each of our reactions. ) Trial 1: (5. 32 x 10^-4 mol / . 165294 l) x (1 mol / x) x= 3. 11 x 10^ 2. Trial 2: (4. 9 x 10^-4 mol / 1. 65861 l) x (1 mol / x) x= 3. 38 x 10^ 2. Trial 1: (1 atm)( x l)/(273. 15 k) x (. 0777 atm)( 310. 7 l)/(294. 17083 k)= 22. 41 l. Trial 2: 1 atm)( x l)/(273. 15 k) x (. 0715 atm)( 338. 5 l)/(294. 59 k)= 22. 44 l.
