While mercury is very useful in barometers, mercury vapor is toxic. Given that mercury has a ΔHvap of 59.11 kJ/mol and its normal boiling point is 356.7°C, calculate the vapor pressure in mm Hg at room temperature, 25°C. Group of answer choices 2.99 mm Hg 753 mm Hg 2.68 × 10-3 mm Hg 372 mm Hg

At 300 mm hg, a gas has a volume of 380 l, what is the volume at standard pressure
