To determine the gas, we need to consider the ideal gas law: P1 * V1 = P2 * V2, where P1 and V1 are the initial pressures and volumes, and P2 and V2 are the final pressures and volumes. We have the pressure (760 torr) and temperature (17°C), but not the volume. Since helium and neon are the only gases with no dipole moment, they follow the ideal gas law perfectly. Methane (CH4) and nitrogen (N2) have dipole moments, which would affect the pressure-volume relationship.

What is the pressure of 1 mole of an ideal gas at 300 K and a volume of 250 cm3?
Using the ideal gas law, PV = nRT, we can calculate the pressure. Given n = 1 mole, R = 0.0821 L atm/mol K, T = 300 K, and V = 0.25 L (250 cm3), we can solve for P, which yields approximately 98.5 atm, making this the correct answer.
