What is the minimum mass that a cloud with these properties needs in order to form a star?

AH PLEASE HELP!

I tried doing this problem, I got about 10733 Msun.... but apparently it's wrong.



Isolated molecular clouds can have a temperature as low as 12 and a particle density as great as 1.5脳105 per cubic centimeter.

I am interested in the answer as well. How did you get your answer? Is it from the Jeans instability of gravitationally bound cloud? This, to me at least, is a pretty advanced problem in interstellar medium course.
