1. What is Mole Ratio?

The mole ratio is the ratio between the amounts in moles of any two compounds involved in a chemical reaction. It's used to convert between quantities of reactants and products in chemical equations.

2. How Does the Calculator Work?

The calculator uses the mole ratio formula:

Where:

• \( n1 \) — Amount of substance 1 (in moles)
• \( n2 \) — Amount of substance 2 (in moles)

Explanation: The mole ratio is derived from the coefficients of a balanced chemical equation or from experimental data.

3. Importance of Mole Ratio

Details: Mole ratios are crucial for stoichiometric calculations in chemistry, allowing chemists to predict amounts of products formed or reactants needed in chemical reactions.

4. Using the Calculator

Tips: Enter the amount of each substance in moles. Both values must be positive numbers. The result is a unitless ratio.

5. Frequently Asked Questions (FAQ)

Q1: How is mole ratio different from mass ratio?
A: Mole ratio compares the number of particles, while mass ratio compares the weight of substances. Mole ratio is more fundamental in chemical reactions.

Q2: Can mole ratio be greater than 1?
A: Yes, mole ratio can be any positive number. A ratio >1 means there are more moles of the first substance than the second.

Q3: How is mole ratio used in stoichiometry?
A: It's used to convert between quantities of reactants and products in chemical equations based on the balanced coefficients.

Q4: What if one of the substances is zero?
A: The calculator requires both values to be positive. A zero would make the ratio undefined (for n2=0) or zero (for n1=0).

Q5: Is mole ratio affected by temperature or pressure?
A: No, mole ratio is independent of physical conditions as it's based on particle counts rather than volumes or masses.
