Part A In order to understand how this equation is derived and why it holds true, the product of each side of the equation should be examined. What value and unit do you get when you multiply a concentration of 0.687 M by a volume of 0.500 L ? This question can be expressed as 0.500 L 1 0.687 mol X L Express your answer to three significant figures with the appropriate units. ► View Available Hint(s) O μÀ ? M₁ V₁ = Value Units Submit Part B When you need to produce a variety of diluted solutions of a solute, you can dilute a series of stock solutions. A stock solution has a significantly higher concentration of the given solute (typically 10¹ to 104 times higher than those of the diluted solutions). The high concentration allows many diluted solutions to be prepared using minimal amounts of the stock solution. What volume of a 6.61 M stock solution do you need to prepare 500. mL of a 0.0579 M solution of MgSO4? Express the volume to three significant figures with the appropriate units.…

SHOW YOUR WORK! Use conversion factors to determine the answers to the Following questions. Do not forget sig figs & units. 37. What is the final M of a solution prepared by diluting 5.0 mL of 6.0 M HCI to 60.0 mL? (2 sig figs)

Thanks in advanced, these are just 4 step problems but this one has me stumped for some reason. Use to being given grams. Zinc metal reacts with hydrochloric acid ( Zn + 2HCl --> ZnCl^2 + H^2 ) You add .156 mole of hydrochloric acid solution to .145 mole of zinc in a beaker and waited several minutes for the reaction to complete. How many moles of ZnCl^2 was produced and what was the limiting reagent, Zn or HCl?
