Question
Give the mathematical expression that relates gas volume and moles.
Advertisements
Solution
- The mathematical relationship betwêen the volume of a gas and the number of moles is V α n
- `"V"_1/"n"_1 = "V"_2/"n"_2` = Constant
Where V1 and n1 are the volume and number of moles of a gas and V2 and n2 are the values of volume and number of moles of the same gas at a different set of conditions. - If the volume of the gas increase then the number of moles of the gas also increases.
- At a certain temperature and pressure, the volume of a gas is directly proportional to the number of moles of the gas.
