Problem: For each set of values, calculate the missing variable using the ideal gas law.

We will use the ideal gas equation to calculate for each of the 

P = pressure, atm
  V = volume, L
  n = moles, mol
  R = gas constant = 0.08206 (L·atm)/(mol·K)
  T = temperature, K

It is important to note the units used for this formula. We can see that our given does not have the same units so we would need to convert.
