1) Determine the change in entropy for the expansion of 0.10 mole of an ideal gas from 2.0L to 3.0 L at constant temperature?

My work: 0.10 mole * (8.314 J/K)/ (1 mole) * ln (3.0L/2.0L) = 0.33 J/K

2) To what fraction of its original volume must a 0.50 mole sample of ideal gas be compressed at constant temperature for change in entropy to be -6.7 J/K?

My work:  0.50 mole * (8.314 J/K)  / ( -6.7 J/K )  ???   I dont know how to solve this problem.
