We use two R values: 0.0821 and 8.314. How do you know which to use for a problem?
The units for pressure
The units for temperature
The units of volume
The amount of moles
In the following, what is the unknown variable:
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
V
n
T
Which of the following variables is NOT correctly matched with its value for this problem:
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
