What pressure is required to contain 0.023 moles of nitrogen gas in a 4.2 L container at a temperature of 20⁰C?

• V = 4.2 L

• R = 0.0821 L⋅atm∕mol⋅K

• n = 0.023 mol

• P = 20⁰C

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)
