1. What is Molar Ratio?

The molar ratio is the proportion of moles of one substance to another in a chemical reaction or mixture. It's a fundamental concept in stoichiometry that helps determine reactant quantities and product yields.

2. How Does the Calculator Work?

The calculator uses the simple ratio formula:

Where:

• Amount A — Moles of substance A
• Amount B — Moles of substance B

Explanation: The ratio is unitless and represents how many moles of A exist per mole of B.

3. Importance of Molar Ratio

Details: Molar ratios are essential for balancing chemical equations, determining limiting reagents, calculating reaction yields, and preparing solutions with specific concentrations.

4. Using the Calculator

Tips: Enter amounts in moles (not grams). Both values must be positive numbers. The calculator will automatically compute the ratio of A to B.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert grams to moles?
A: Divide the mass in grams by the substance's molar mass (g/mol).

Q2: What's the difference between mass ratio and molar ratio?
A: Mass ratio uses weights (grams), while molar ratio uses molecular quantities (moles).

Q3: How is molar ratio used in stoichiometry?
A: Coefficients in balanced equations represent molar ratios of reactants and products.

Q4: What does a ratio of 2:1 mean?
A: It means there are 2 moles of substance A for every 1 mole of substance B.

Q5: Can the ratio be greater than 1?
A: Yes, when there's more of substance A than B. A ratio less than 1 means more of B than A.
