Question

how much 0.100 m stock solution in ml do you need to make 100.0 ml of 0.0614 m solution of nacl? the molar mass of nacl is 58.44 g/mol. we are expecting the answer rounded to the correct number of significant figures. your answer:

Answer 1

To make 100.0 mL of 0.0614 M NaCl solution, you will need 61.4 mL of the 0.100 M stock solution.

Step-by-step explanation:

To calculate the amount of 0.100 M stock solution needed to make 100.0 mL of 0.0614 M NaCl solution, we can use the formula:

V1 * C1 = V2 * C2

Where

V1 is the volume of the stock solution

C1 is the concentration of the stock solution

V2 is the final volume of the diluted solution

C2 is the desired concentration of the diluted solution

Using this formula, we can rearrange it to solve for V1:

V1 = (V2 * C2) / C1

Substituting the given values, we have:

V1 = (100.0 mL * 0.0614 M) / 0.100 M = 61.4 mL

Therefore, you will need 61.4 mL of the 0.100 M stock solution to make 100.0 mL of the 0.0614 M NaCl solution.
