I NEED HELP WITH NUMBER 2 PLEASE I WILL GIVE EXTRA POINTS!!

2) consider the model we have developed to represent molecules of a gas at room temperature. You may remember that the volume of a gas is roughly 1000 times as great as that of a liquid. With this in mind predict
The volume of a mole of another gas say N2 or CO2 at STP. Justify your prediction.

PLEASE HELP ME OUT :)

Fill in the blanks for the following statements: the rms speed of the molecules in a sample of h2 gas at 300 k will be times larger than the rms speed of o2 molecules at the same temperature, and the ratio µrms (h2) / µrms (o2) with increasing temperature. a not enough information is given to answer this question b sixteen, will not change c four, will not change d four, will increase e sixteen, will decrease
