Document Summary
R = 8. 314 j/molk = 0. 08206 l atm/molk. 1 atm = 760 torr = 101. 325 kpa. There are 8 pages in this quiz including the cover page and the periodic table. Check and make sure you have answered each question before handing in the quiz. Magnesium-lithium alloy is used where its extremely low density is a desirable property. A piece of this alloy having a mass of 0. 0297 g is analysed by adding hcl (aq). The liberated hydrogen gas was collected over water at 19 c and at atmospheric pressure of 746 torr. Calculate the percentages of magnesium and lithium in the alloy. The water vapour pressure at the temperature of collection was 16. 48 torr. (5) The fat stored in the hump of a camel is a source of both energy and water. Gaseous iodine pentafluoride, if5 can be prepared by the reaction of solid iodine and gaseous fluorine according to the reaction:
