Question: If 4.12L of a 0.850M-H3PO4 solution is be diluted to a volume of 10.00L, what is the concentration of the resulting solution?

Short Answer

Expert verified

If 4.12L of a 0.850M-H3PO4 solution is diluted to a volume of 10.00L, the concentration of the resulting solution is 0.350M.

Step by step solution

01

Summarize the given data

The data we are given:

Initial Volume of H3PO4 solution, V1= 4.12L

Initial Molarity of H3PO4 solution, M1= 0.850M

Final Volume of H3PO4 solution, V2 = 10.00L

To find:

Final Molarity of H3PO4 solution, M2 =?

02

Determine the concentration of the resulting solution

The formula needs to be used to solve the problem:

M1V1= M2V2

Substituting the equation, we get,

0.850M × 4.12L = M2 × 10.00L

i.e., M2 = 0.350M
