the density of a sample of cobalt is determined to be 10.2 g/cm³ at room temperature. What is the percent error for the determined value? Be sure to round to the tenths and do not include units.

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.
