Answer: It is true for the process used to achieve the required dilution that volume of the solvent used is less than 2 liters.

Explanation:

Given: M_{1} = 10 M,       V_{1} = ?

M_{2} = 1 M,       V_{2} = 2 L

The volume of stock solution is calculated as follows.

M_{1}V_{1} = M_{2}V_{2}\\10 M \times V_{1} = 1 M \times 2\\V_{1} = 0.2 L

A solution which contains small amount of solute is called a dilute solution. Whereas a solution which contains more amount of solute is called a concentrated solution.

The stock solution is used for dilution and hence, it acts as a solvent. Its calculated volume is 0.2 L.

This means that volume of the solvent used is less than 2 liters.

Thus, we can conclude that it is true for the process used to achieve the required dilution that volume of the solvent used is less than 2 liters.

According to the concept of the tragedy of the commons, what happens to shared resources over time?
Maslowich
I would believe the answer to this question is D. According to the concept of the tragedy of the commons, shared resources are used by more than one organism. Due to the large consumption of shared resources they start to be fewer and fewer in number and over time if we are not careful they will be depleted.
