calculate the volume of concentrated nitric acid, if 18 moldm-³ is required to prepare 2.0 moldm-³ nitric acid
To calculate the volume of concentrated nitric acid, we need to use the equation:
C₁V₁ = C₂V₂
Where C₁ is the concentration of the concentrated nitric acid, V₁ is the volume of the concentrated nitric acid, C₂ is the concentration of the desired nitric acid, and V₂ is the volume of the desired nitric acid.
In this case, C₁ is unknown, C₂ is 2.0 moldm-³, V₂ is also unknown, and 18 moldm-³ is the volume of diluted nitric acid.
We can rearrange the equation to solve for V₁:
V₁ = (C₂V₂) / C₁
Substituting the given values:
V₁ = (2.0 moldm-³) * (18 moldm-³) / C₁
Since we don't know the value of C₁, we cannot calculate the volume of concentrated nitric acid without knowing its concentration.
