Problem 14.010 - Composition of a gas mixture
A gas mixture has the following composition on a mole basis: 76 percent O$_2$ and 24 percent CO$_2$. Determine the gravimetric analysis of the mixture, its molar mass, and the gas constant. The universal gas constant is $R_u = 8.314$ kJ/kmol·K. Use the table containing the molar mass, gas constant, and critical-point properties.
The mass fraction of O$_2$ is ______ %.
The mass fraction of CO$_2$ is ______ %.
The molar mass of the mixture is ______ kg/kmol.
The gas constant of the mixture is ______ kJ/kg·K. (Round the final answer to three decimal places.)
