Ideal Gas Law is the expression that describes the relationship among the four variables: temperature, pressure, volume, and the number of moles of a gaseous substance under a given set of conditions. The derived relationship for density is given by the equation: d = pWRT. The Ideal Gas Law equation is represented as: Pl = nRT, where Pl is the pressure, n is the number of moles, R is the ideal gas constant, and T is the temperature. The value of the ideal gas constant can be either 0.0821 atm mol or 8.314 L mol K.
What pressure is exerted by 25 g of nitrogen gas in a flask with a volume of 250 mL at 20 °C? The pressure is equal to 4.14 atm.
