What was the temperature change of the metal? C) Calculate the specific heat and the atomic mass of the metal. What is the metal?
What is the mole fraction of pentane in a pentane-hexane solution that has a vapour pressure of 308 torr at 25 oC? (At 25 oC the vapour pressure of pure pentane is 511 torr and that of hexane is 150 torr.)
A piece of lithium metal was added to a flask of water on a day when the atmospheric pressure was 757.5 Torr. The lithium reacted completely with the water to produce 250.0 mL of hydrogen gas, collected over the water at 23°C, at which temperature..
