Document Summary

Professor dill -- office hours: tuesday, wednesday, thursday 4pm-5pm in sci/200b. (1. 2kg/m^3) (2000m^3) = 2408 kg = mass of liquid: given information: use the composition of air to determine the volume by each individual element. i. ii. Composition: 75. 5% n2, 23. 2% o2 and 1. 3% ar. Densities of liquid: 0. 808g/cm^3 n2, 1. 141g/cm^3 o2, 1. 3954 g/cm^3 ar: solve for only the volume of n2. (0. 755) (2408 kg) = 1800 kg = 1. 80 x 10^6 g. 0. 808 g/cm^3 = (1. 82 x 10^6 g) / (x cm^3) X = 2. 2 x 10^6 cm^3 = 2. 2 m^3.
