When a sample of HBr (g) was placed inside a sealed container at 600 K, with a pressure of 1.93x10^6 Pa, the density of the gas was experimentally found to be 40 g/L. What is the compression factor Z for this gas under these conditions? What sort of intermolecular forces are dominating at these conditions: attractive or repulsive?

Which of the following statements is true about the compressibility factor (Z)? When Z is greater than 0, attractive forces between the particles dominates. When Z is less than 0, attractive forces between the particles dominates. Z steadily increases for an ideal gas. Z equals 24.79 L bar for an ideal gas. Repulsive forces between particles cause Z to be less than 0 at high pressures.
