"IDEAL GAS, PRESSURE, VOLUME, TEMPERATURE, MOLES, GRAMS, MOLECULAR WEIGHT, DENSITY. Ideal gases follow the behavior expressed in the ideal gas law: P * V = N * R * T gas constant R=0.0821 atm∙L/(mole ∙ K) R=8.31 J/(mole ∙ K) where P is pressure in Pascals/atm, V is volume in liters, N is moles and T is temperature in Kelvin (°C +273). Further, N = grams/(molecular weight) and density = grams/volume. Select R for either Pascals or atm. Enter any 4 of theremaining 5 variables as nonzero. The unknown is entered as 0. Program will calculate all 5 variables, moles and density. (c) Copyright PCSCC, Inc., 1993 *** Answer(s) to problem *** STP (standard temp and pressure) is T=273 K and p=1 atm and v=22.4 l. Set G=0, MW=18 (2*1+16), P=1, R=0.0821, T=273 and V=22.4. Program will calculate the grams of water at STP and its density = 0.8030946 g/liter.
