    				| 1. | Give the mathematical expression that relates gas volume and moles. Describe in words what the mathematical expression means | 
| Answer» (i). The mathematical relationship between the volume of a gas and the number of moles is V ∝ n (ii). \(\frac{V_1}{n_1}=\frac{V_2}{n_2}\) = 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 same gas at a different set of conditions. (iii). If the volume of the gas increase then the number of moles of the gas also increases. (iv). At a certain temperature and pressure, the volume of a gas is dirctly proportional to the number of the moles of the gas. | |
