• 106.55 K

• 53.3 L

• 293 K

• 64.15 L

What is the correct value for T in the following problem:

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

• T = 0.23 K

• T = 293 K

• T = 4.2⁰C

• T = 20⁰C

Solve the following probem:

What pressure is required to contain 0.23 moles of nitrogen gas in a 4.2 L container at a temperature of 20⁰C?

• 1.32 atm

• 0.048 atm

• 2.49 atm

• 19.32 atm

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

In the ideal gas law, P = ​ (a)   , V = ​ (b)   , n = ​ (c)   ,

R = ​​ (d)   , and T = ​ (e)
