Imperial Units?
« on: May 18, 2007, 02:53:09 AM »
How does the g-mol differ from the lb-mol?

Is 1 g-mol = 1 lb-mol?

OR

since 1 1b = 453.59 g then 1 lb mol = 453.59 g-mol

Imperial units are fine for buying food but crap for science.

Yes probably, but I can't be sure since I don't know what you mean by "g-mol"

1 lb mol = 453.59 g mol in any case.

I have not much of a choice. The equations stated in this book for estimating installation, purchase and operation cost of a chemical unit operation are in Imperial Units.

Yes probably, but I can't be sure since I don't know what you mean by "g-mol"

Apparently, the SI mole unit we use corresponds to the g-mol.

So 1 lb = 453.58g means 1 lb-mol = 453.59 g-mol = 453.59 mol

Thanks for clearing this up for me :D
