1. What is a Molar Ratio Calculator?

Definition: This calculator determines the ratio of moles between two substances in a chemical reaction or mixture.

Purpose: It helps chemists, students, and researchers understand the proportional relationships between reactants and products in chemical equations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R \) — Molar ratio (dimensionless)
• \( n₁ \) — Moles of substance 1 (mol)
• \( n₂ \) — Moles of substance 2 (mol)

Explanation: The ratio is calculated by dividing the moles of the first substance by the moles of the second substance.

3. Importance of Molar Ratio

Details: Molar ratios are crucial for stoichiometric calculations, determining limiting reagents, and preparing solutions with specific concentrations.

4. Using the Calculator

Tips: Enter the moles of both substances (must be positive values). The ratio will be calculated automatically.

5. Frequently Asked Questions (FAQ)

Q1: What does a molar ratio of 2:1 mean?
A: It means there are twice as many moles of substance 1 compared to substance 2.

Q2: How do I find the moles of a substance?
A: Use the formula: moles = mass (g) / molar mass (g/mol).

Q3: Can the ratio be greater than 1?
A: Yes, when substance 1 has more moles than substance 2.

Q4: What's the significance of molar ratio in reactions?
A: It shows the proportional relationship between reactants and products as shown in balanced chemical equations.

Q5: Does the order of substances matter?
A: Yes, R = n₁/n₂ is different from R = n₂/n₁. Be consistent with which substance is numerator and denominator.
