Pascal vs Atmosphere

Postby DAllaf » Tue Nov 28, 2017 10:31 pm

When solving for partial pressure is it better to use pascal or atmosphere? Are there situations in which one is better than the other? Does Lavelle prefer one over the other?

Lavelle uses atm for the purposes of Chem 14A (at least it says so in his course reader).

Lavelle does prefer atm however you need to double check what the original units are for the partial pressure given and match those units. if no units are given but an R (gas constant) value is given, double check to see whether that value of R represents the pressure in atm or bar.

I would just follow whichever unit is given in the question, though from lecture it seems that atm are more prevalent than Pa.
