1 answer

To rearrange the equation \( PV = nRT \), you want to isolate one variable on one side of the equation. Here are the rearrangements for each response option:

  1. R = nTPV: Incorrect, because this does not isolate \( R \).
  2. T = \(\frac{PV}{nR}\): Correct rearrangement, because it isolates \( T \).
  3. n = \(\frac{PV}{RT}\): Correct rearrangement, because it isolates \( n \).
  4. R = PV - nT: Incorrect, this does not follow from the original equation.

The best answers for proper rearrangements are:

  • T = \(\frac{PV}{nR}\)
  • n = \(\frac{PV}{RT}\)

Both are valid rearrangements depending on which variable you are solving for.
