Consider a mole of CO2 and a mole of N2O each at STP. Which of the following statements are true? Check all that apply.

Question

~Both gases will have approximately the same density at these conditions.
~When the volume is not held constant, raising the temperature will decrease the density of both samples
~The CO2 sample will contain fewer molecules of gas.
~When the volume is held constant, raising the temperature will increase the density of both samples.
~N2O will have a higher density at these conditions.
~Both samples will occupy the same volume.

Answer 1

Both gases will have approximately the same density at these conditions.

When the volume is held constant, raising the temperature will increase the density of both samples.
