Convert the volume of CO2 you measured in the glucose reaction to moles of CO2 using the Ideal Gas Law to solve for n. Assume P is 1 atm. n = PV/RTwhere P is the atmospheric pressure in the lab, V is the volume in liters of CO2, n is the number of moles of CO2, R is the gas constant 0.082 L-atm/mole-Kelvin, and T is the temperature in Kelvin. Convert the gas volume to L by dividing the volume in mL by 1000.
