Find pH: \(pH = -\log(2.5 \times 10^{-5}) \) → (tap twice) → 2.5 5
Find [H+]: \( 10^{-3.5} \) (tap twice) → 3.5
Solve \( PV=nRT \) for \( n \) ( P * V ) ( 0.0821 * T )
Using the Fraction Tool

To solve \( n = \frac{PV}{RT} \) without errors:

  1. Press the key.
  2. Enter your Numerator (\( P \times V \)).
  3. Press the bottom edge of the silver circular pad to move the cursor down.
  4. Enter your Denominator (\( R \times T \)).
  5. Press .
