  2. Enter the known values.  

  3. Click Calculate.  

  4. The result (V₂ or M₂) will be displayed.  

📌 Formula: 

$$M_1{V}_1=M_2{V}_2$$

C. pH/pOH Calculator  

How to Use? 

  1. Select the calculation type from the dropdown (e.g., [H⁺] → pH).  

  2. Enter the value.  

  3. Click "Calculate".  

  4. The result (pH, pOH, [H⁺], or [OH⁻]) will appear.  

📌 Formulas:  

$$pH=-\log [H^{+}],pOH=-\log [O{H}^{-}],pH+pOH=14$$

D. Ideal Gas Law Calculator  

How to Use?
