Chemy 101, Experiment 7 Data Sheet, Determining The Molar Mass Of a Gas Student name: 1.D#: ........... See No.: .......... Results & Calculations. 34.016 1- Mass of flask filled with air m 34.076 2- Mass of flask filled with gas m 136.516 3- Mass of flask filled with water my - g 4- Room temperature = 21°C + 273 = 296 K 5 - Atmospheric pressure - 760 mmHg - 1 atm 6- Density of air under conditions of experiment - 0.00122g /em' 7- Mass of water = m-m 8- Density of water = 1g/cm 9. Volume of water muso/d20 step 7 / step 8 cm 10- V.4.20 V. fak - V.gas-V.. cm 11- Mass of air mir die V.le-step 6 x step 10 - 12- Mass of empty flask = m - m ir = step 1 - step 11 = 13- Mass of gas = m - m flank = step 2 - step 12 = 14- Molar mass of a gas = m.gas x RXT/PxV 15- MM - step. 13 g * (0.0821 L .atm/ K.mol) x 296 K latm step. 10 x 10 L 16 - MM of the gas = g/mol 17 - The gas is 18- The theoretical Molar Mass from periodic table = TO TO 3/mol 19-% Error= (Actual MM - Theoretical MM) / Theoretical MM x 100
