Standard entropies for substances are defined at a pressure of exactly 1 bar or exactly 1 atm in different books. For gases, this correction factor would be..... in J/molK?

Answer is in format 0.xxxxxx

I'm a little confused... I'd appreciate any help.

1 atm= 1.013 25 bar or
1 bar= 0.986923 atm

Is that what it means by correction factor?

The answers you provided were not in J/mol*K... instead they were just conversions... is that what the question is asking?

The question above further asked if this would apply to solids and liquids, and the answer is 'no'.
