Calculating actual yield of CO2
• d) The amount of gas collected in the first trial is __________mL and in the second trial is ___________mL. Change the volume of CO2 trapped in your bottle from milliliters to liters. Calculate the average volume of CO2 in liters. AVERAGE amount of CO2 collected is ________L.
• e) Use the Ideal Gas Law, PV = nRT, to calculate number of moles of CO2 trapped in your bottle. This is the actual yield of CO2. Assume that P is 1.0 atm and T is 293 K (room temperature). The gas constant, R, is (0.0821 liter-atm / mole-K); V is AVERAGE volume of trapped CO2 in liters calculated in (d); and n is the average number of moles of CO2 trapped in your bottle O2
n = PV/RT = {1 atm x V} / {(0.0821 L-atm / mole-K) x (293 K)}
You don't have to worry this long equation because it boils down to a simple equation that you use:
actual yield in moles = n = V x 0.0416
First, fill in the value for the AVERAGE volume of CO2 collected, V. The actual yield of CO2 is _________moles
