Question

70 POINTS your own answer , i got two different and need to get this question correct.

What is the molarity of 30.0 mL of hydrochloric acid solution after 15.0 mL of a 3.00 M solution has been diluted? ___ M (Answer Format X.X)

Answer 1

Answer: The molarity of the hydrochloric acid solution after dilution is 1.5 M.

Explanation: To calculate the molarity of a solution after dilution, you can use the formula M1V1 = M2V2 where M1 is the initial molarity of the solution, V1 is the initial volume of the solution, M2 is the final molarity of the solution, and V2 is the final volume of the solution.

In this case, we have 15.0 mL of a 3.00 M solution that has been diluted with water to a final volume of 30.0 mL. Using the formula above, we can calculate the final molarity as follows:

M1V1 = M2V2 (3.00 M)(15.0 mL) = M2(30.0 mL) M2 = (3.00 M)(15.0 mL) / (30.0 mL) M2 = 1.50 M

So, the molarity of the hydrochloric acid solution after dilution is 1.5 M

Hope this helps, and have a great day! =)
