What volume of 0.25 M hydrochloric acid (HCl) solution contains 0.15 mol HCl?

• A. 0.15 L
• B. 0.38 L
• C. 0.25 L
• D. 0.60 L

Answer: (D)

Verified step by step guidance

1. Identify the known values: the molarity (M) of the HCl solution is 0.25 M, and the amount of HCl in moles (n) is 0.15 mol.
2. Recall the definition of molarity, which relates moles of solute to volume of solution: \(M = \frac{n}{V}\), where \(M\) is molarity, \(n\) is moles of solute, and \(V\) is volume in liters.
3. Rearrange the molarity formula to solve for volume: \(V = \frac{n}{M}\).
4. Substitute the known values into the rearranged formula: \(V = \frac{0.15\ \text{mol}}{0.25\ \text{mol/L}}\).
5. Calculate the volume \(V\) in liters to find the volume of 0.25 M HCl solution that contains 0.15 mol of HCl.
