**Answer:**

You may be saving someone from a rock slide, where the rocks will fall at any time, before they fall they have potential energy.

The type of solution which contains higher than normal amounts of osmotically active solutes is called a hypertonic solution. This is a solution where the concentration of the solutes inside the cell is higher than the concentration outside the cell. The opposite is called a hypotonic solution.

**Answer : The volume of 6M NaOH stock solution is, 16.7 mL**

**Explanation :**

**To calculate the volume of NaOH stock solution, we use the equation given by neutralization reaction:**

where,

are the molarity and volume of NaOH stock solution.

are the molarity and volume of NaOH.

**We are given:**

Putting values in above equation, we get:

**Thus, the volume of 6M NaOH stock solution is, 16.7 mL**
