Experiment 1-Airbag Report Sheet Name________________________________ Lab Partners__________________________ GSI:____________________ _____________________________________ Table 1. Airbag Data Trial Mass of NaHCO 3 (grams) Volume of 6M CH 3 COOH (mL) Total mass of apparatus (grams) Theoretical volume of bag (L) Experimental volume of bag (L) 1 2 3 4 5 6 7 8 9 10 Calculations: 1) For the first experiment, you reacted approximately 0.5 g of NaHCO 3 with 6M acetic acid, CH 3 COOH. Using the actual mass of NaHCO 3 you weighed, calculate the volume (in mL) of acetic acid needed to react with the NaHCO 3 . 2) Calculate the theoretical volume of the airbag using the reactant amounts of your first trial in liters. At room temperature (25ºC), the volume of 1 mole of gas is about 24.5 L.

Unformatted text preview: 3) Using the length, width, and height measurements you made of your bag, calculate the experimentally determined volume of the airbag in liters. Results and Discussion: 1) Was the airbag volume in your first experiment larger or smaller than predicted? 2) What could be the source(s) of the difference between the theoretical and experimental volume of the bag? 3) Did the 1:1 ratio of NaHCO 3 to CH 3 COOH reaction go to completion? How can you tell? 4) What chemistry strategies did you employ to maximize the volume of CO 2 produced by your airbag? 5) What mechanical strategies did you employ to maximize the volume of CO 2 produced by your airbag? 6) Would this method be suitable for inflating automobile airbags? Why or why not?...
