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 determine the relative quantities of reactants and products in chemical reactions.

2. How Does the Calculator Work?

The calculator uses the mole ratio formula:

Where:

• \( Moles\ A \) — Amount of substance A in moles
• \( Moles\ B \) — Amount of substance B in moles

Explanation: The ratio compares the number of moles of one substance to another, which is fundamental in stoichiometric calculations.

3. Importance of Mole Ratio

Details: Mole ratios are essential for balancing chemical equations, determining limiting reactants, 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 is a mole in chemistry?
A: A mole is the SI unit for amount of substance, defined as exactly 6.02214076×10²³ particles (atoms, molecules, ions, etc.).

Q2: How is mole ratio used in stoichiometry?
A: Mole ratios from balanced equations are used to convert between amounts of reactants and products in chemical reactions.

Q3: Can mole ratio be more than 1?
A: Yes, the ratio can be any positive number. A ratio >1 means more moles of substance A, <1 means more moles of substance B.

Q4: What's the difference between mole ratio and mass ratio?
A: Mole ratio compares number of particles, while mass ratio compares weights. They differ when substances have different molar masses.

Q5: How accurate is mole ratio calculation?
A: The calculation is mathematically exact, but practical accuracy depends on precise measurement of the actual moles of each substance.
