Q
Describe how to set up the apparatus to measure the volume of gas produced in a reaction
A
A gas syringe or an upside-down water-filled measuring cylinder in a trough of water may be used to collect the gas
2
Q
How can the number of moles of CO2 be calculated from the volume of CO2collected during an experiment?
A
• If at room temperature and pressure (RTP), use the equation n=V/24 where V is the volume in dm3
•If not at RTP, rearrange the ideal gas law PV=nRT and plug in the numbers for R (8.31), T in kelvin, P in pascals and V in m3
