Question

Show your work to calculate the concentration for the following sample using C₁V₁ = C₂V2

3.5 mL of Bromophenol Blue (0.2 mg/mL) and 0.5 mL distilled H₂0

Answer 1

The answer is 412

Step-by-step explanation:

Because we distracted c1 from h2o due to the chemical combination of the two

Answer 2

Step-by-step explanation:

To calculate the concentration of the resulting solution, we can use the formula C₁V₁ = C₂V₂, where C₁ is the initial concentration, V₁ is the initial volume, C₂ is the final concentration, and V₂ is the final volume.

Given:

C₁ = 0.2 mg/mL

V₁ = 3.5 mL

V₂ = V₁ + 0.5 mL = 3.5 mL + 0.5 mL = 4 mL (assuming no significant change in volume upon mixing)

Using the formula, we can solve for C₂:

C₁V₁ = C₂V₂

0.2 mg/mL * 3.5 mL = C₂ * 4 mL

0.7 mg = C₂ * 4

C₂ = 0.7 mg / 4 mL

C₂ ≈ 0.175 mg/mL

Therefore, the concentration of the resulting solution is approximately 0.175 mg/mL.
