1. The problem statement, all variables and given/known data Suppose that you measured the product pV of 1 mol of a dilute gas and found that pV = 22.98 L atm at 0°C and 31.18 L atm at 100°C. Assume that the perfect gas law is valid, with T = t(°C) + a, and that the value of R is not known. Determine R and a from the measurements provided. Express your result for R in J K -------------- 2. Relevant equations PV = nRT T = t(°C) + a 3. The attempt at a solution Ok I answered the first part: R = slope = (31.18 - 22.98 / 100 - 0 ) = 0.082 L atm C what is a ??how do I find it??
