Question 8 (5 points)

(08.02 MC)
A 10 M concentrated stock solution of NaCl was used to prepare 5 liters of diluted 1 M solution. Which of the following statements is true about
the
process used to achieve this required dilution? (5 points)
O a
The volume of stock solution used was less than 0.4 liters.
Oь
The volume of stock solution used was more than 5 liters.
Ос
The volume of the solvent used was less than 0.4 liters.
Od
The volume of the solvent used was less than 5 liters.

Answer 1

The volume of the solvent is less than 5

Step-by-step explanation:

Answer 2

d . The volume of the solvent used was less than 5 liters.

Step-by-step explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the volume of the stock (initial) solution by using the following equation:

`M_1V_1=M_2V_2`

Thus, we solve for, V1, which stands for the aforementioned volume of stock solution:

`V_1=(M_2V_2)/(M_1)`

Then, we plug in to obtain:

`V_1=(5L*1M)/(10M)\\\\V_1=0.5L`

Now, since the final volume was 5 L, we can infer that the volume of solvent is 4.5 L and that of the stock solution 0.5 L for a total of 5 L of diluted solution; therefore, the correct reasoning is d . The volume of the solvent used was less than 5 liters.

Regards!
