For an equimolar solution of n-pentane and n-hexane, compute: a) the dew-point pressure at 1450f b) the bubble-point temperature at 2.3 bar c) the vapor fraction, at 145.f and 0.75 atm, and the mole fractions of the vapor and liquid phases d) report the critical temperature, pressure and find the msds of both chemicals

The density of an unknown gas at 98°c and 740 mmhg is 2.50 g/l. what is the molar mass of the gas with work showed?
