Question

What volume of 2.00 M phosphoric acid can be made from 300.0 mL of a concentrated 14.8 M solution?

A) 40.5 mL
B) 20.2 mL
C) 4050 mL
D) 2020 mL

Answer 1

The correct volume of 2.00 M phosphoric acid made from 300.0 mL of 14.8 M solution is 4440 mL, which is not listed in the given options.

Step-by-step explanation:

To find the volume of 2.00 M phosphoric acid that can be made from 300.0 mL of a concentrated 14.8 M solution, we can use the dilution formula: M1V1 = M2V2, where M1 is the concentration of the initial solution, V1 is the volume of the initial solution, M2 is the concentration of the final solution, and V2 is the volume of the final solution.

Inserting the known values into the formula, we have: (14.8 M)(300.0 mL) = (2.00 M)(V2).

Solving this equation for V2 gives us:

V2 = (14.8 M)(300.0 mL) / (2.00 M) = 4440 mL or 4.440 L

Therefore, the correct answer is not given in the options A) 40.5 mL, B) 20.2 mL, C) 4050 mL, or D) 2020 mL, as the calculated volume is 4440 mL.
