1. What is Molar Ratio?

The molar ratio is the ratio between the amounts in moles of any two compounds involved in a chemical reaction. It's a fundamental concept in stoichiometry used to predict product yields and reactant requirements.

2. How Does the Calculator Work?

The calculator uses the simple molar ratio formula:

Where:

• \( n1 \) — Number of moles of first substance
• \( n2 \) — Number of moles of second substance

Explanation: The ratio represents how many times more moles of one substance there are compared to another.

3. Importance of Molar Ratio

Details: Molar ratios are crucial for balancing chemical equations, determining limiting reagents, and calculating theoretical yields in chemical reactions.

4. Using the Calculator

Tips: Enter the number of moles for both substances. Both values must be positive numbers. The result is a unitless ratio.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between molar ratio and mass ratio?
A: Molar ratio compares the number of particles (moles), while mass ratio compares the weights. They differ when substances have different molecular weights.

Q2: How is molar ratio used in stoichiometry?
A: It's used to convert between quantities of reactants and products using the coefficients from a balanced chemical equation.

Q3: What does a 2:1 molar ratio mean?
A: It means there are twice as many moles of the first substance as the second substance.

Q4: Can molar ratio be greater than 1?
A: Yes, when n1 > n2. It's less than 1 when n1 < n2, and exactly 1 when equal amounts are present.

Q5: Is molar ratio affected by temperature or pressure?
A: No, the ratio of moles remains constant regardless of conditions, though the actual number of moles might change with conditions.
