See attachment ecxample001.

2. Relevant equations

See attachment D11.

3. The attempt at a solution

In the first equation (Cp/R = a+bT+cT^2...etc.), Cp/R is the constant pressure specific heat. The general formula for enthalpy change is h2-h1 = integral[Cp]dT, so does Cp/R = Cp except Cp/R is the constant pressure specific heat on a molar basis?

Then in the next line of formula in the solution (h2-h1 = R/M integral (a+bT...)dT) how did it go from Cp/R to R/M? I'm totally lost in this. And by the formula do I seriously plug in these huge numbers (from D11)? I tried plugging it in and get keep getting somethign to the 17th power. I'm also very confused on the units, as there's a lot of variables and I'm not very clear on them and what they represent. Any help would be appreciated. Thanks!
