Calculate the mass of air in a classroom. Assume a classroom of side lengths 8.00 m, 7.00 m, and 3.00 m, containing air with a density of 1.225 kg/m3.
Calculate the depth to which Avogadro’s number of table tennis balls would cover Earth. Each ball has a diameter of 3.75 cm. Assume the space between balls increases their volume by and assume they are not crushed by their own weight. Use km as the value of the Earth’s radius.
Find the height of Earth’s atmosphere. Use a value of kg for the mass of the atmosphere, a value of 1 kg/m3 for the atmosphere’s density, and a value of km for Earth’s radius.
