Choose the correct set of variables to solve the following problem: What is the volume of a balloon if it contains 3.2 moles of helium at a temperature of 20⁰C and 1.2 atm?
P = x (unknown), V = 3.2 mol, n = 1.2 atm, T = 20⁰C K
P = 1.2 atm, V = 3.2 mol, n = 20⁰C, T = x (unknown)
P = 293 K, V = 3.2 mol, n = x (unknown), T = 1.2 atm
P = 1.2 atm, V = x (unknown), n = 3.2 mol, T = 293 K
