Two flasks of equal volume and at the same temperature contain different gases. One flask contains 10.0 g of Ne, and the other flask contains 10.0 g of He. Is each of the following statements true or false? Explain.1) True. Because the gases have the same mass, they exert the same pressures.2) True. Both the volumes and the temperatures of the gases are the same, which means that their pressures must be equal.3) False. There are different numbers of moles in the flasks, meaning that the pressures are different.
