(HELP PLEASE) At a certain temperature and pressure, one liter of CO2 gas weighs 1.35 g. What is the mass of one liter of N2 gas at the same temperature and pressure? (do I have to get the moles to get the answer? I am quite lost in this)

OpenStudy (jfraser):

you do have to find the moles of \(CO_2\), and because the pressure, temp, and volume of the two gases are the same, then the moles will also be equal.
