What is the concentration of HCl in the final solution when 65 mL of a 12 M HCl solution is diluted with pure water to a total volume of 0.15 L? A)2)8 × 10^-2 M B)5)2 M C)28 M D)5)2 × 10³ M

Question

Using the dilution formula:

M1V1 = M2V2

where: 
M1 = initial concentration of HCl solution 
V1 = initial volume of HCl solution 
M2 = final concentration of HCl solution 
V2 = final volume of solution

Plugging in the values:

(12 M)(65 mL) = M2(150 mL)

M2 = (12 M)(65 mL) / (150 mL) 
M2 = 5.2 M

Therefore, the concentration of HCl in the final solution is 5.2 M.
