Molar Mass Determination:

Molar Mass Determination Use IGE to determine molar mass of a gas from experimental data number of moles (n)= Substitute this identity in, and the IGE becomes: Molar mass ( M ) =

Practice Problem :

Practice Problem Suppose we measure the mass of the vapor of an unknown compound contained in a 273 mL gas bulb. We find that the bulb contains 0.750 g of gas at 97.2 kPa pressure and 61 ºC. What is the molar mass ( M ) of the gas? = 78.5 g/mol Convert mL to L by moving the decimal point 3 places to the left
