Answer to Problem 7.30E
The values of
Explanation of Solution
The
The conversion of temperature in Celsius to Kelvin is given by the formula,
Substitute the value of
Thus, the temperature of the ideal solution is
The molar mass of pentane is calculated as,
Thus, the molar mass of pentane is
The molar mass of hexane is calculated as,
Thus, the molar mass of hexane is
