A 10 liter tank containing oxygen under the pressure of 1.5 MPa, the other cylinder volume of 22 l containing helium under a pressure of 0.6 MPa at the same temperature. Cylinders and connected to form a homogeneous mixture of gases without changing the temperature. Determine the partial pressure, the concentration of molecules and weight of the mixture components, if the rotational movement of the gas molecules have to energy 4.14 * 10-21 J.

Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
