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
