About Molar Ratios
Molar ratios express the relative amounts of substances in moles. They are fundamental in stoichiometry and chemical calculations.
From Moles:
Ratio = Moles A : Moles B
From Mass:
Ratio = (Mass A / MW A) : (Mass B / MW B)
Stoichiometric:
Moles Target = Moles Given × (Coeff Target / Coeff Given)
Molar ratios are essential for:
- Balancing chemical equations
- Calculating limiting reagents
- Determining theoretical yields
- Preparing solutions with specific ratios
