Naima Pace · Answer 1

D) 0.450 M

Explanation:

Given data

Initial volume (V₁) : 6.00 mL Initial concentration (C₁) : 0.750 M Volume of water (VH₂O) : 4.00 mL Final volume (V₂) : V₁ + VH₂O = 6.00 mL + 4.00 mL = 10.0 mL Final concentration (C₂) : ?

We can determine the final concentration using the dilution rule.

C₁ * V₁ = C₂ * V₂

C₂ = C₁ * V₁/V₂

C₂ = 0.750 M * 6.00 mL/10.0 mL

C₂ = 0.450 M
