What volume of 0.220 M HBr solution (in mL) is required to obtain 0.0600 moles of HBr?

• A. 132 mL
• B. 273 mL
• C. 0.220 mL
• D. 0.0132 mL

Answer: (B)

Verified step by step guidance

1. Identify the known quantities: the molarity of the HBr solution, \(M = 0.220\ \text{M}\), and the amount of moles of HBr needed, \(n = 0.0600\ \text{moles}\).
2. Recall the definition of molarity, which relates moles of solute to volume of solution: \(M = \frac{n}{V}\), where \(V\) is the volume in liters.
3. Rearrange the molarity formula to solve for volume: \(V = \frac{n}{M}\).
4. Substitute the known values into the equation: \(V = \frac{0.0600}{0.220}\) liters.
5. Convert the volume from liters to milliliters by multiplying by 1000: \(V_{mL} = V \times 1000\).
