What NaCl concentration results when 284 mL of a 0.850 M NaCl solution is mixed with 467 mL of a 0.380 M NaCl solution

0.558 M.

Explanation:

Hello!

In this case, when computing the resulting concentration of the solution after a mixing process, we first need to compute the moles provided by each solution:

So the total number of moles are:

And the total volume which is additive:

Therefore, the resulting molarity of sodium chloride is:

Best regards!

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
