The density of ordinary air is 1.19 g/L. What is the mass, in kilograms, of the airin a room that measures 14.5 ft x 16.5 ft x 8.0 ft?(Hint: Density is defined as d= m/v, so you need to find the volume of the roomand solve for the mass in the density equation. Make sure you do the appropriateconversions to carry out your operations. Use the correct number of significantfigures to express your answer).

The Apothecary system of units was used in Britain and the US until 1858. Given the density of water is approximately 28000g/ft3 and the relationships below, show all you work in calculating the density in apothecary pounds per pint. In the Apothecary system of units, gallons, quarts and pints are equivalent to those in the English system of units. 1 grain = 0.0.065 g, 20 grains = 1 scruple, 3 scruples = 1 dram, 8 drams = 1 apothecary ounce, 12 apothecary ounces = 1 apothecary pound.
