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

Isolated molecular clouds can have a temperature as low as 12 K and a particle density as great as 1.50脳10^5 particles per cubic centimeter.What is the minimum mass that a cloud with these properties needs in order to form a star?
I think only about 10% of the mass of the cloud goes to form the star, the rest gets blown away since a young star gets hot too quickly to allow much more mass to accrete into it.What is the minimum mass that a cloud with these properties needs in order to form a star?
Whoa that's extremely complicated and intense. Well compared to the other questions. I'll get back to you once I ask my science teacher.
