Conversion of Heat Unit

What is the unit Kw?

Kilowatt

how to convert 241.8 kJ/g-mol (at 298.15 K) or 0.0672 kWh/g-mol to BTU/Hr/Kw

1. You need to keep your unit designations consistent. There is no way you can be sloppy here without confusion. For kilowatts, it should ALWAYS be written kW, not Kw.
2. Your units of BTU/Hr/kW does not make sense: Both BTU/Hr and Kw are units of power. This gives you power/power, a dimensionless expression.
3. Your initial units of kJ/g-mol and kWh/g-mol are energy/mass. To convert them, the end units must be in the same configuration (take some time to ponder this).

Either you did not represent the end units correctly, or you are trying to do something that is impossible.

I suggest that you repost your question and take your time to make sure it is right. If you want to understand this, it is no time to be lazy.

Better still, work in the SI system, then there's no need to convert (to BTU/lb-mol, presumably)

Codey

I really wish we would. I hate having all these conversion factors in my head! It's too full already!

We coat adhesives and do lamination of roll stock. To determine the correct amount, we get the coat weight by weighing a piece of paper, sticking it on the web, pulling it off with the adhesive on it, and weighing again.

We use a paper cutter with inch rulings and a balance that reads in grams. Thus we have the cool mixed units of g/100in².

I suggest you go here to learn how to do this:

Happy studying!
