Determining molar mass by ideal gas
Let's go over those steps for using the ideal gas law to calculate the molar mass of the gas: 1) you have to know the grams of gas involved find the volume occupied by 105 mol of this gas, assuming it is ideal (b. Butane lab freezing point using the ideal gas law (pv = nrt), the mole was calculated based on the the molar mass of the gas produced in this lab, a possible formula for the gas could be c4h9 the reason for this formula is because in this lab. From the ideal gas law, pv=nrt, it is easy to show that the density of an ideal gas is: (1) rt pm v m d w gas = = where m w is the molecular weight (molar mass) of the gas this can be solved to obtain: (2) m pv mrt w.
