We are asked to place the following gases in order of decreasing the average molecular speed at 28 oC: Ne, HBr, SO2, NF3, CO.
The higher the molar mass, the lower the speed of the molecule.
Molar mass Ne = 20.18 g/mol
Molar mass HBr = 80.91 g/mol
Molar mass SO2 = 64.07 g/mol
Molar mass NF3 = 71.01 g/mol
Molar mass CO = 28.01 g/mol
Place the following gases in order of decreasing average molecular speed at 28 oC: Ne, HBr, SO2, NF3, CO.
