Question

This is for the last question "I am not sure how to answer 6a-d"

Also if you could answer 4 and 5 as well 

**Osmosis**

Red blood cells are isotonic with a NaCl solution that is 0.90% (m/v) NaCl, also known as Normal Saline (NS), and 5% glucose, also known as D5W (dextrose, 5% in water). Dextrose is the same as glucose. Intravenous fluids must be isotonic to avoid cell lysis (by bursting) or the opposite effect, shriveling or crenation.

**6. A cell that is isotonic with D5W is placed in a 10% (m/v) glucose solution.**

a) Where is the higher concentrated solution (inside the cell or outside the cell)?

b) In which solution is the amount of water relative to the solute higher (inside the cell or outside the cell)?

c) Which direction will water flow to equalize the concentrations (into the cell or out of the cell)?

d) Will the cell swell or crenate?

**Problem 4: Dilution of Saline Solution**

- **Question:** If you added 800 mL of water to 250 mL of a normal saline solution (0.9% m/v), what would the concentration of the new solution be?

**Problem 5: Dilution of Glucose Solution**

- **Question:** What is the final concentration if 85 mL of a 2.50 M glucose solution is diluted to a volume of 550 mL?

**Explanation:**

*These problems involve the concept of dilution and concentration in solutions. The common formula used for dilution is:*

\[ C_1V_1 = C_2V_2 \]

*Where \( C_1 \) and \( V_1 \) are the initial concentration and volume, and \( C_2 \) and \( V_2 \) are the final concentration and volume.*
