Calcium chloride was apparently discovered in the 15th century but wasn't studied properly until the 18th century. [11] It was historically called "fixed sal ammoniac" (Latin: sal ammoniacum fixum [12]) because it was synthesized during the distillation of ammonium chloride with lime and was nonvolatile (while the former appeared to sublime); in more modern times (18th-19th cc.) it was called ...
New York: The International Nickel Company, Inc., 1941: 16. — "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T.

While calcium is a poorer conductor of electricity than copper or aluminium by volume, it is a better conductor by mass than both due to its very low density. [13] While calcium is infeasible as a conductor for most terrestrial applications as it reacts quickly with atmospheric oxygen, its use as such in space has been considered. [13]
Baumé degrees (heavy) originally represented the percent by mass of sodium chloride in water at 60 °F (16 °C). Baumé degrees (light) was calibrated with 0 °Bé (light) being the density of 10% NaCl in water by mass and 10 °Bé (light) set to the density of water. Consider, at near room temperature:
An active search is underway for a 66-year-old Michigan woman who disappeared from a popular tourist hot spot during a trip to the Grand Canyon more than a week ago, officials said.
