Molar Ratio Formula:
From: | To: |
The molar ratio is the ratio between the amounts in moles of any two compounds involved in a chemical reaction. It's a dimensionless quantity that shows the proportional relationship between reactants and products.
The calculator uses the simple molar ratio formula:
Where:
Explanation: The ratio compares the number of moles of one substance to another, which is fundamental in stoichiometric calculations.
Details: Molar ratios are crucial for balancing chemical equations, determining limiting reagents, and calculating theoretical yields in chemical reactions.
Tips: Enter the moles of both substances (must be positive numbers). The calculator will compute their ratio (A:B). The result is dimensionless.
Q1: What's the difference between molar ratio and mass ratio?
A: Molar ratio compares number of particles (moles), while mass ratio compares weights. Molar ratio is more useful for chemical reactions.
Q2: How do I find moles from molar ratio?
A: If you know the ratio and one quantity, multiply the known moles by the ratio to find the unknown moles.
Q3: Can molar ratio be greater than 1?
A: Yes, when substance A is present in greater molar quantity than substance B, the ratio will be >1.
Q4: Where is molar ratio used in real applications?
A: Used in pharmaceutical formulations, industrial chemical production, and laboratory reagent preparation.
Q5: How does molar ratio relate to stoichiometric coefficients?
A: The coefficients in a balanced chemical equation represent the molar ratios of reactants and products.
