Asolution is made by dissolving 373.5 g of pb(no3)2 (molar mass: 331.2 g/mol) in 2.00 × 103 g of water. what is the molality of the solution?

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
