Answer:
the resulting solution is 1.5 M.
Step-by-step explanation:
To solve this problem, we can use the dilution formula:
M1V1 = M2V2
where M1 is the initial concentration, V1 is the initial volume, M2 is the final concentration, and V2 is the final volume.
We are given that 15.0 mL of a 3.00 M hydrochloric acid solution has been diluted, and we want to find the molarity of the resulting solution. Let's use M1 for the initial concentration, V1 for the initial volume, M2 for the final concentration, and V2 for the final volume.
M1 = 3.00 M
V1 = 15.0 mL
V2 = 30.0 mL (since 15.0 mL has been diluted to 30.0 mL, the final volume is 30.0 mL)
We can rearrange the dilution formula to solve for M2:
M2 = (M1V1) / V2
Substituting the given values, we get:
M2 = (3.00 M x 15.0 mL) / 30.0 mL
M2 = 1.50 M
Therefore, the molarity of the resulting solution is 1.5 M.
