Document Summary

Combining the above 3 expressions / laws we get the ideal gas law. Pv = nrt where r is called the gas constant. 1v1 / n1t1 = r = p2v2 / n2t2 or just p1v1 / n1t1 = p2v2 / n2t2. Because the amount of gas usually do not change, the equation becomes. However, this only describes the pressure of an ideal gas. Molecules of an ideal gas do not attract or repel each other. Their volume is negligible to the volume of the container. Ideal gas law also breaks down at low temperatures and high pressures. At standard temperature and pressure aka stp (273. 15 k and 1 atm): 1 mole of ideal gas occupies 22. 414 l. Density and molar mass of a gaseous substance. D = m / v = pm / rt where m is molar mass. Note: when calculating pressure of gas collected over. A = nart / v water, pt = pa + ph2o.
