Question 4. Select the best answer by circling A, B or C below, and if applicable, fill in the number of grams. a) You work as a summer student in a lab to help a postdoctoral fellow in her research. One day she left on your bench a small vial containing 6 g of vitamin Z powder and a note asking you to prepare 20 ml of a 1M solution while she attends a seminar (use water to make the solution, she wrote). You start this task by checking the molecular weight of Vitamin Z (300 g/mol). When the postdoc comes back from the seminar: A You complain that there is not enough powder and you need g more to prepare this solution. B You give your solution to the postdoc and thank her for having calculated the exact amount of powder needed. (but you think that she could have told you that!) C You return the leftover g to the postdoc together with the solution.

Solution 1 is diluted by adding 519 microliters of Solution 1 to 5 mL of Solution 2. What is the dilution of Solution 1? Report your answer in standard decimal notation rounded to 2 decimal places. Include trailing zeros so that two decimal points are reported. For example, 500 μL added to 5 mL would be a 0.09 dilution or 50 μL added to 4.5 mL would be a 0.10 dilution.
