Question

What volume of a 1.00-M Fe(NO₃)₃ solution can be diluted to prepare 1.00 L of a solution with a concentration of 0.250 M?

a) 0.25 L
b) 0.50 L
c) 0.75 L
d) 1.00 L

Answer 1

The volume of the 1.00-M Fe(NO₃)₃ solution that can be diluted to prepare a 1.00 L solution with a concentration of 0.250 M is a. 0.25 L.

Step-by-step explanation:

To find the volume of a 1.00-M Fe(NO₃)₃ solution needed to prepare a 1.00 L solution with a concentration of 0.250 M, we can use the dilution equation:

C1V1 = C2V2

Where C1 and V1 are the initial concentration and volume, and C2 and V2 are the final concentration and volume respectively.

Plugging in the values, we have:

(1.00 M)(V1) = (0.250 M)(1.00 L)

Simplifying the equation, we find that:

V1 = 0.250 L

Therefore, the volume of the 1.00-M Fe(NO₃)₃ solution that can be diluted to prepare a 1.00 L solution with a concentration of 0.250 M is a. 0.25 L.
