- One component of a metal sculpture consists of a solid cube with an edge of length 36.9 cm. The alloy used to make the cube has a density of 6610 kg/m³. Find the cube's mass. m = kgA cubical box with sides of length 0.247 m contains 1.110 moles of neon gas at a temperature of 320 K. What is the average rate (in atoms/s) at which neon atoms collide with one side of the container? The mass of a single neon atom is 3.35x10-26 kg. Number i UnitsA container of gas holds 0.74 moles of neon gas. If the volume of the container is 11.8 liters and the pressure inside is 1.97 atm, what is the temperature (in K) of the gas?
