hydrometer
a hofmann voltameter is often used as a demonstration of stoichiometric principles, as the two-to-one ratio of the volumes of hydrogen and oxygen gas produced by the apparatus illustrates the chemical formula of water, ho. however, this is only true if oxygen and hydrogen gases are assumed to be diatomic. if hydrogen gas were monatomic and oxygen diatomic, the gas volume ratio would be 4:1.









































the volumetric composition of water is the ratio by volume of hydrogen to oxygen present. this value is 2:1 experimentally; this value is determined using hofmann's water voltameter.

richard coar









































richard j. coar (may 2, 1921 – december 29, 2013), an aeronautical engineer, was a member of the united states national academy of engineering, elected in 1984.









































the american society of mechanical engineers honored him with the george westinghouse medal in 1984, and in 1998 he received the daniel guggenheim medal.









































he received a bachelor's degree from tufts college in 1942. he is known for helping develop the model 304 liquid hydrogen aircraft engine, and the rl10 rocket engine. he later served as executive vice president at pratt & whitney.
