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
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
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.
Answer:
The answer is 412
Explanation:
Because we distracted c1 from h2o due to the chemical combination of the two
