Question

Learning Goal: To understand how to determine the appropriate formula for a given gas law problem. When you are unsure of which formula to use to solve a gas law problem, it is often helpful to make a chart of initial and final values of pressure P, volume V, number of moles n, and temperature T, as show in table. You are confronted with the following question: One mole of an ideal gas is sealed in a 22.4-L, container at a pressure of 1 atm and a temperature of 273 K. The temperature is then increased to 305 K, but the container does not expand. What will the new pressure be? The most appropriate formula for solving this problem includes which variables? Enter the required variables, separated by commas. For example: P,V,T. Your answer does not have the correct number of comma-separated terms. This question will be shown after you complete previous question(s). Solve the problem stated in the problem introduction by finding the new pressure. Express your answer with the appropriate units.

Explanation / Answer

idel gas equation is applying here PV = nRT so now container is sealed so volume and moles are fixed so P/T = nR/V = constant so P1/T1 = P2/T2 1/273 = P2/305 P2 = 1.1172 atm
