Question

using the table find the theoretical number if moles of CO2 produced for each trial.

trial mass E Caco, /g volume volume room initial final volume volume of of HCI of vial temp. pressure pressure of tube flask/ml /ml / ml. /K 7 torr torr / mL 10.00 1.96 295.95 8.0 137.8 261.32 10.00 1.96 295.81 7.7 135.7 5.96 261.32 10.00 1.96 295.77 7.9 138.1 5.96 261.32 0.1949 0.2114 0.2000

Answer 1

For trial1 a= 0.1949 g og beoritical yield of ca & = 0.1949 mol = 1.949 410-3 mol For tor) all = 0.214 g og neoritiat yield of cor = 0.21146 mol – 2.114x10 mol 100 For trials a=0.2000 g greoritica gield ofcon - 0.2000 moh. 2.0*10 wot. 100
