Calculate the change in chemical potential of an ideal gas when its pressure is increased isothermally from 1.8 atm to 29.5 atm at 40 C.
A solution is prepared by adding 1.10 g of solid rm NaCl to 50.0 mL of 0.100 M {CaCl_2}. What is the molarity of chloride ion in the final solution? Assume that the volume of the final solution is 50.0 mL.
Gases diffuse faster compared to liquids because of the reason that the liquid molecules A. are held together by stronger inter-molecular forces.
