2 Avogadro’s Hypothesis At a constant temperature and pressure , a given volume of gas always has the same number of particles. The coefficients of a balanced reaction is the same ratio as the volumes of reactants and products
3 2CO (g) + O 2 (g) 2CO 2 (g) For the above example, it is understood that half the volume of oxygen is needed to react with a given volume of carbon monoxide. This can be used to carry out calculations about volume of gaseous product and the volume of any excess reagents.

4 Example • 10cm 3 of ethyne (C 2 H 2 ) is reacted with 50cm 3 of hydrogen to produce ethane (C 2 H 6 ), calculate the total volume and composition of the remaining gas mixture, assuming constant T& P. 1 st get balanced equation: C 2 H 2 (g) + 2H 2 (g) C 2 H 6 (g) 2 nd look at the volume ratios: 1 mol ethyne to 2 mol of hydrogen, therefore 1 vol to 2 vol 3 rd analyse: If all 10cm 3 of ethyne is used, it needs only 20cm 3 of hydrogen, therefore hydrogen is in excess by 50cm 3 -20cm 3 = 30 cm 3 . In the end you’ll have 10 cm 3 Ethane and the leftover 30 cm 3 hydrogen
5 Molar volume The temperature and pressure are specified and used to calculate the volume of one mole of gas.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
