How many osmoles would be in a 116 g/mole of NaCl solution? (10 points) I 16. If glucose is needed to enter inside the cell of the intestines, which ion is required? Which type of transporter brings glucose into the blood stream? Describe the role of the Na/k pump in the body's ability to uptake glucose (10 points) E

Answer 1

Ans 15: Given value is NaCl = 58 grams/ mole

• To prepare a molar solution of NaCl, 58 grams of NaCl is dissolved in water to make volume upto 1 litre. So. its 1Molar NaCl solution.

• To prepare a molal solution of NaCl, 58 grams of NaCl is dissolved in 1 kilogram of water. So, its 1 Molal NaCl solution.

• Molarity of NaCl solution containing 116g/moles = 116/ 58 = 2 M,

So, number of osmoles of 2M NaCl solution = Molarity X Number of particles in the solution

= 2 x 2 = 4 osmoles in solution.
