1.00 ft3 of steam at 300.°F and 14.7 psia is mixed with 3.00 ft3 of methane at 80.0°F and 14.7 psia. Assuming ideal gas behavior for both of these substances, determine
a) The mass fractions.
b) The mole fractions.
c) The pressure fractions.
d) Both the constant pressure and constant volume specific heats of the mixture.
