Have any one tried to run the matlab script that the prof had sent example 4,20 ? I have an error and could not figure it out. if any one had encounter the same problem and solve it please tell us where is the error.

What is the error exactly. When I run the code, I do not receive any error, so I’m not sure what the problem is. I assume you are running the code in your MoLE-SI account.

Yes I used MoLE-SI to access Matlab the error is “Error: File: problem420.m Line: 73 Column: 1
Function definitions are not permitted in this context.”

OK, we’ll discuss in class. I do not get this error message. In fact, there is no code on “line 73” of my Problem420.m file.

Homework 2-12 doesn’t make sense.

Is the exam out of 115 or 135?
September 14th, 2015 at 2:57 pm
The exam scores are out of 130 points. Sorry about the addition error on the exam score sheet.

Alisa, I believe you mean problem 4-12 in Chapter 4. I can go over this problem in class, however, it requires that you perform integration as show in Section 4.5.1 and given by equations (4-70) and (4-72).
I hope this helps,

in problem 4-20
we should get the density for (xylenes) from appendix
i found the density of o-xylene and m-xylene and p-xylene
so do we take the average for the (xylenes) density???
