6-2. 6-3. 6-4. 6-5. An unknown compound has the following composition, by mass: 46.2% C, 5.17% H, and 48.7% F. The molar mass of the compound is experimentally determined to be 468 g/mol. Determine the empirical and molecular formulas for this compound. A solution is prepared by mixing 175 mL of a 2.48 M (NH4)3PO4 solution with enough water to make a total of 3.00 liters of solution. What is the molarity of ammonium ions in this new solution? Use only dimensional analysis to solve this problem. Include a number, unit, and substance in the numerator and the denominator for every conversion fraction used. A solution is prepared by dissolving solid iron(III) bromide in water. If the solution has a concentration of 0.438 M FeBr3 then how many grams of iron(III) bromide were dissolved in a 75.0 mL sample of this solution? Household bleach is an aqueous solution of sodium hypochlorite. Suppose you have a 355 mL sample of household bleach which has a density of 1.08 g/mL and is 5.25% NaCIO by mass. What is the molarity of sodium hypochlorite in household bleach?
