1.   You were hired to work for Thermoline Analytical Lab, Inc, as a laboratory technician. Your supervisor asked you to prepare a 25 mL, 0.10 M sucrose solution and label it with compositions, formulas, molarity and density. How do you accomplish your job?

2.   You were working in a biomedical research lab. You needed to find 25 mL of 1.5x10-3 M aqueous solution of blue dye for your next experiment. After a thorough search, you found a bottle of 0.01M, stock solution of the blue dye. How do you dilute the stock solution to the concentration you needed?

Consider the two lab questions mentioned in the front page of this learning module. How could you do to answer these questions in the lab? What are the experimental steps that you should follow to prepare the solutions required in the questions?You need to write a procedure that contains step-by-step instructions to be followed in the lab. The written procedure must be detailed enough for anyone, not just yourself, to follow in the lab. Your procedure will be graded based on this principle.
