Question
**Problem 1: Bromophenol Blue (BPB) Solution Preparation** Bromophenol blue (BPB) is a blue dye that comes in powdered form. If you need to prepare 35 ml of a 0.1 mg/ml BPB solution, how many milligrams of BPB will you need to add to 35 ml of water? Show your work below. **Calculation Explanation:** To find the amount of BPB needed, use the formula: \[ \text{Concentration} = \frac{\text{Amount of solute (mg)}}{\text{Volume of solution (ml)}} \] Given: - Concentration = 0.1 mg/ml - Volume = 35 ml Calculate the amount of BPB: \[ \text{Amount of BPB} = \text{Concentration} \times \text{Volume} = 0.1 \, \text{mg/ml} \times 35 \, \text{ml} \] \[ \text{Amount of BPB} = 3.5 \, \text{mg} \] You need to add 3.5 mg of BPB to 35 ml of water to achieve the desired concentration.
