Answer :
Final answer:
To calculate the volume of the 1.5M HCl solution needed, use the formula C1V1 = C2V2. Plugging in the given values, the volume is calculated to be 61.6mL.
Explanation:
To calculate the volume of a 1.5M solution of HCl needed to make a 0.4M solution, you can use the formula:
C1V1 = C2V2
Where C1 is the concentration of the initial solution, V1 is the volume of the initial solution, C2 is the concentration of the final solution, and V2 is the volume of the final solution.
Plugging in the values, we have:
1.5M * V1 = 0.4M * 229.8mL
Simplifying the equation:
V1 = (0.4M * 229.8mL) / 1.5M
Calculating the volume:
V1 = 61.6mL (to one decimal place)
