8.6 At 25°C, B = -42 cm³/mol for CH, and B = -732 cm³/mol for n-C,H10. For a mixture of 0.0300 mol of CH, and 0.0700 mol of n-C,H10 at 25°C in a 1.000-L vessel, calculate the pressure using the virial equation and (a) the approximation B12 = (B, + B,); (b) the fact that for this mixture, B = -180 cm³/mol. Compare the results with the ideal-gas-equation %3D %3D 12 result.
