Hexane (C6H14) and heptane (C7H16) are both volatile liquids that form ideal solutions over the full range or compositions when mixed together. Given the vapor pressures of pure hexane (121 mmHg) and heptane (40 mmHg) at 20°C, what is the vapor pressure of heptane over a hexane-heptane solution at 20°C when it contains mole fraction of hexane (Xhexane) equal to 0.75? A) 101 mmHg B) 91 mmHg C) 81 mmHg D) 30 mmHg E) 10 mmHg pure
