2.5 g of Glucose is dissolved in enough water to make 1 L of solution. What is the molarity (M) of the solution? How many moles of glucose are contained in 237 mL of the above glucose solution? What volume (L) of this glucose solution would contain .079 moles of glucose?

Explanation:

we know , molar mass of glucose is 18.08 g

now , moles of glucose =

                                    =

                               = 0.138 moles of glucose .

Molarity =

            =

         =0.138 M glucose or moles/litre.

      Number of moles of glucose contained in 237ml of glucose =

= 0.0327 moles glucose.

               = (by using the molarity formula)

               = 0.572 L of glucose .

Hence ,

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
