A 10 M concentrated stock solution of NaCl is used to prepare 2 liters of diluted 1 M solution. Which of the following is true for the process used to achieve the required
dilution? (5 points)
O The volume of the solvent used is less than 0.1 liters.
O The volume of stock solution used is less than 0.1 liters.
The volume of stock solution used is more than 2 liters.
The volume of the solvent used is less than 2 liters.

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: = 10 M,       = ?

= 1 M,       = 2 L

The volume of stock solution is calculated as follows.

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.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
