1. A cylinder contains a mixture of hydrogen and chlorine molecules. Compare without doing any calculations:

a) the relative mass of the molecules

since atomic mass of chlorine is more than Hydrogen, therefore chlorine has higher relative mass.

b) the temperature of each gas

since, relative atomic mass is directly related to temperature, therefore, chlorine will have more temperature.

c) the ...

  • Temperatures and Pressures for Gas Laws

    This is an application of Dalton's Law of Partial Pressures. Therefore: P = 0.45 atm + 0.25 atm + 0.60 atm = 1.30 atm (iii) We can arrive at this answer by using the ideal gas law, PV = nRT and rearranging it into the form, V = nRT/P.
