Question 392206: I have a class to take in a couple of weeks and I am not sure about my pre test questions.
1. if Q = AV solve for V ?
2. If SP H = (1 + f h ) VPduct, solve for F h?
3. Mole fraction = X 1 = (X1=X2) ser up a numerical example.

Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
1. if Q = AV solve for V ?
Divide both sides by "A" to get:
V = Q/A
======================

2. If SP H = (1 + f h ) VPduct, solve for F h?
Subtract "1" from both sides to get:
fh = SP H - 1
================
The 3rd problem doesn't make any sense.
================
