QUESTION 4 A flask has 1.50 moles of hydrogen gas at 30.0 °C and a pressure of 375 mm Hg. After the addition of more hydrogen gas at the
same temperature, the pressure rises to 1.50 atm. How many moles of hydrogen gas are added? 1 atm - 760 mm Hg.

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.
