Question

You have 3.00 L of a 3.74 M solution of NaCl(aq) called solution A. You also have 2.00 L of a 2.00 M solution of AgNO3(aq) called solution B. You mix these solutions together to make solution C. Calculate the concentration (in M) of Cl ions in solution C.

Answer 1

Answer:

$M=2.24M$

Explanation:

Hello!

In this case, since the molarity and volume of the solutions are given, we are able to compute the moles of chloride ions as they are present in NaCl only:

$n_{Cl^-}=3.00L*3.74\frac{molNaCl}{L}*\frac{1molCl^-}{1molNaCl} =11.22molCl^-$

Next, since the mixing of solution A and B lead to a volume of 5.00 L, the concentration of chloride ions turns out:

$M=\frac{11.22mol}{5.00L}=2.24M$

Best regards!
