Core Calculations Supported

1. Molarity Calculation

Formula:$$M = \frac{\text{moles of solute}}{\text{liters of solution}}$$M=liters of solutionmoles of solute​

Required Inputs:

• Moles of solute
• Volume in liters

Output:

• Molarity (mol/L)

---

2. Dilution Evaluation

Formula:$$M_1V_1 = M_2V_2$$M1​V1​=M2​V2​

Required Inputs:

• Initial concentration (M₁)
• Initial volume (V₁)
• Final concentration (M₂) or Final volume (V₂)

Output:

• Missing value from the equation

---

3. pH Calculation

For acids:$$pH = -\log[H^+]$$pH=−log[H+]

Required Inputs:

• Hydrogen ion concentration

Output:

• pH value

Practical Examples

Example 1: Molarity

You dissolve 2 moles of NaCl in 1 liter of water.$$M = 2 ÷ 1 = 2M$$M=2÷1=2M

Result: 2 mol/L

---

Example 2: Dilution

Initial concentration = 5M
Initial volume = 1L
Final concentration = 1M$$5 × 1 = 1 × V_2$$5×1=1×V2​

V₂ = 5L

---

Example 3: pH Calculation

Hydrogen ion concentration = 0.001 mol/L$$pH = -\log(0.001) = 3$$pH=−log(0.001)=3
