by the heightof mercury in the pressure gauge divided by the height ofmercury in the barometer, was removed. Having calculated, then, the number of cubic centimetersof air admitted and its weight, we may readily compute theweight of 1000 cm.3. Since the weight of air varies greatly with the… … Fig. 15 SPECIFIC GRAVITY OF A LIQUID 29 Arrange the data and calculated results in an orderlyfashion and draw a diagram of the apparatus. Problem. If one cubic foot of air weighs about 1.3 ounces,how many pounds of air are contained in a schoolroom whichis 40 feet x 30 feet x 12 feet? EXPERIMENT 15…
