Question

Forming Mixtures Using the ideal gas model with constant specific heats, determine the mixture temperature, in K for each of two cases: (a) Initially, 0.6 kmol of O2 at 500 K is separated by a partition from 0.4 kmol of H2 at 300 K in a rigid insulated vessel. The partition is removed and the gases mix to obtain a final equililbrium state. (b) Oxygen (02) at 500 K and a molar flow rate of 0,6 kmolls enters an insulated control volume operating at steady state and mixes with H2 entering as a separate stream at 300 K and a molar flow rate of 0.4 kmol/s. A single mixed stream exits. Kinetic and potential energy effects can be ignored. Step-by-step solution

Explanation / Answer

Instead of mass they have given the number of moles of O2 and H2 and by multiplying with their molecular masses 32g and 2.016g you can get the weight of these molecules .And putting these values in equation you can get same result .
