Find the molarity of a solution prepared by dissolving 120 g CaCl2 (MW = 111 g/mol) in 450 cm3 of solution.
Write all of the resonance structures for o-bromonitrobenzene. Draw a structure for the octahedral complex from the reaction of p-chlorobenzohydroxamic acid with ferric chloride.
How much NaOH in grams is needed to prepare 546 mL of solution with a pH of 10.00? The molecular weight of NaOH is 40.0 g/mol. Hint: Since NaOH is a strong base it ionizes (disassociates) completely. The OH- concentration equals the initial concen..
