CELL BIOLOGY PRACTICE SOLUTION PROBLEMS 1. You have 50 ml of an 86% (w/v) glucose (C 6 H 12 O 6 ) solution. a. How many grams of glucose are in the solution? b. Using the above solution, how would you prepare 100 ml of a 19% (v/v) solution? How many grams of glucose are in this solution? 2. You have a bottle containing 500 g CaCl 2 . a. Describe how you would prepare 200 ml of a 0.2 M solution of CaCl 2 . b. What is the % concentration of CaCl 2 in the solution described in 2a? 3. You start with 50 ml of a 1 M solution of K 2 HPO 4 . If you add 3 ml of the above solution to 17 ml of water a. what is the final molarity of the solution? b. what is the concentration of K

Unformatted text preview: 2 HPO 4 in the solution in mg/ml? 4. You asked Joe Solution to prepare a 40% solution of sucrose as part of an interview for a research job. He added 40g of sucrose to a beaker and then added 100 ml of water to the beaker and stirred it until the sucrose dissolved. Would you hire Joe for the position? Why? 5. Using a dye that stains for all major macromolecules you obtain the standard curve shown below. Estimate the concentration of the macromolecules in your original sample (in mg/ml) of 4 ml of 25% v/v dilution of the original sample. The absorbance you measure with your 25% v/v solution is 0.6.
