Try this, Anna:

2500 kcal/mol * 1000 / 0.23 = 575000 N*m/mol
575000 N*m/mol * 10^9 * 10^12 = 5.75*10^26 pN*nm/mol
5.75*10^26 pN*nm/mol * 6.02*10^-23 * #molecules in your system ~ 200
kBT

with 4.2 pN*nm = 1 kBT

200 kBT is about the amount of work it takes to unfold RNA or a
multidomain protein. Please post corrections if you find a mistake
with my calculation...
