QUESTION: Problem 92P
Assuming that the volumes are additive, what is the concentration of KBr in a solution prepared by mixing 0.200 L of 0.053M KBr with 0.550 L of 0.078 M KBr?
ANSWER:
Solution 92P:
Here, we are going to calculate the concentration of KBr in a solution prepared.
Step 1:
Given that,
For solution 1:
Volume of KBr = 0.2 L
Molarity of KBr = 0.053 M = 0.053 mol/L
For solution 2:
Volume of KBr = 0.550 L
Molarity of KBr = 0.078 M =0.078 mol/L
We know that,
Molarity =
