1. Use dimensional analysis, proper significantfigures & show units. A white powder found at a crimescene was sent to the lab for identification. The lab determined itto contain 60.00% C, 4.48% H, and 35.52% O. What is the empiricalformula of this unidentified white powder?
2. Use dimensional analysis, proper significant figures& show units. Methyl-salicylate,HC8H7O3, is the principalcomponent of Oil of Wintergreen.
(a) What is the mass percent of oxygen in methyl-salicylate?
(b) What would be the mass of methyl-salicylate that contained3.24 kilograms of oxygen?
(c) Methyl-salicylate, is a weak monoproticacid. Write the equation for the equilibrium reaction that occurduring the dissociation of methyl-salicylate,HC8H7O3, in water.
