Gas X has a density of 2.60g/L at STP. Determine the molar mass of this gas.
Sorry there was some typos on the previous question.
please show me again steps by steps. thank you =]
Same answer. You just left the g off the density.
One mole of ANY (ideal) gas occupies 22.4 L at STP. You know how much 1 L weighs. Calculate the mass of 22.4 L. (We always assume the gas is ideal unless the problem says it isn't.)
