1. What is Molar Ratio?

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

2. How Does the Calculator Work?

The calculator uses the simple formula:

\[ \text{Molar Ratio} = \frac{\text{Moles A}}{\text{Moles B}} \]

Where:

Explanation: The ratio compares the quantities of two substances in a chemical context, allowing for precise measurement of their proportional relationship.

3. Importance of Molar Ratio

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

4. Using the Calculator

Tips: Enter the moles of both substances (must be positive numbers). The calculator will compute their ratio. For accurate results, use consistent units for both inputs.

5. Frequently Asked Questions (FAQ)

Q1: Can molar ratio be greater than 1?
A: Yes, when there are more moles of substance A than substance B, the ratio will be greater than 1.

Q2: What does a molar ratio of 2:1 mean?
A: It means there are twice as many moles of substance A compared to substance B.

Q3: 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.

Q4: Is molar ratio the same as mass ratio?
A: No, molar ratio compares number of particles (moles), while mass ratio compares weights. They're only equal when molar masses are identical.

Q5: Can I use this for solution preparation?
A: Yes, molar ratios are commonly used to prepare solutions with specific stoichiometric relationships between components.
