If the decomposition of 0.0150 mol KCIO3 produces 1.80 g KCl, what is the percent yield? The molar mass of KCl is 74.55 g/mol. 2KCIO3(s) + 302(g) + 2KCI(S). (1) 0.83% (2) 83% (3) 90% (4) 62% (5) No answer is correct A Moving to the next question prevents changes to this answer.

Aluminum–lithium (al-li) alloys have been developed by the aircraft industry to reduce the weight and improve the performance of its aircraft. a commercial aircraft skin material having a density of 2.47 g/cm3 is desired. compute the concentration of li (in wt%) that is required.
