69. One cylinder volume V1 = 10 L contains oxygen at a pressure p1 = 1.5 MPa, the other cylinder volume V2 = 22 L contains nitrogen at a pressure P2 = 0.6 MPa. After connecting the gas cylinders were mixed to form a homogeneous mixture (without changing the temperature). Find partial pressures P1 and P2 in the gas mixture as well as the total pressure p of the mixture.
