Final answer:
To make 6 mL of a 10% albumin solution from a 30% albumin solution, you need 2 mL of the 30% solution. This is calculated using the dilution formula C1V1 = C2V2.
Step-by-step explanation:
To solve this problem, we can use the concept of dilution, which involves reducing the concentration of a solution by adding solvent. In this case, we want to dilute a 30% bovine albumin solution to obtain 6 mL of a 10% albumin solution.
We can use the formula C1V1 = C2V2, where C1 and V1 are the concentration and volume of the initial solution, and C2 and V2 are the concentration and volume of the final solution.
- First, plug in the values: (30%)(V1) = (10%)(6 mL).
- Next, solve for V1: V1 = (10% × 6 mL) / 30% = 2 mL.
- Therefore, you would need 2 mL of the 30% bovine albumin to make 6 mL of a 10% solution.
The correct answer is b. 2 mL of 30% bovine albumin are needed.
