3. 4. How do the coefficients for the sodium hydroxide and copper(II) sulfate in the balanced chemical equation compare to the ratio of volumes in the test tube that produced the most precipitate? If you were to use 3.40 mL of 0.250 M copper(II) sulfate in an experiment similar to the one you just completed, what volume of 0.250 M sodium hydroxide would you need so that neither was a limiting reactant? Clearly, but briefly, explain in words the reasoning behind your answer. 5. If a test tube contains 2.65 x 10³ mole of copper(II) sulfate in solution, how many grams of solid copper(II) sulfate are dissolved in the solution? Show your work using dimensional analysis. 6. How many moles of copper(II) sulfate would be needed for a complete reaction with 7.80 x 102 mole of sodium hydroxide? Show your work using dimensional analysis.
