What volume of concentrated phosphoric acid is required to prepare 250ml of a 0.375mol/L solutions?
What concentration of Phosphoric acid?
.00642L
To determine the volume of concentrated phosphoric acid needed to prepare the desired solution, you can use the formula:
C₁V₁ = C₂V₂
Where:
C₁ = concentration of the concentrated phosphoric acid solution
V₁ = volume of the concentrated phosphoric acid solution
C₂ = desired concentration of the final solution
V₂ = volume of the final solution
In this case, we want to prepare a 0.375 mol/L solution with a volume of 250 ml. The concentration of the concentrated phosphoric acid solution is unknown, so let's assume it as C₁.
Now we can rearrange the formula to solve for V₁:
V₁ = (C₂V₂) / C₁
Substituting the given values:
C₂ = 0.375 mol/L
V₂ = 250 ml
The final equation becomes:
V₁ = (0.375 mol/L * 250 ml) / C₁
To find the volume of concentrated phosphoric acid required, we need to know the concentration of the concentrated phosphoric acid solution (C₁).
