GENERAL KNOWLEDGE

Detailed explanation-1: -A “mole ratio” is a conversion factor derived from the coefficients of a balanced chemical equation interpreted in terms of moles. What happens in “chemical calculations"? In “chemical caculations", “mole ratios” are used to convert between moles of reactants and moles of products.

Detailed explanation-2: -A mole ratio is a conversion factor that relates the amounts in moles of any two substances in a chemical reaction. The numbers in a conversion factor come from the coefficients of the balanced chemical equation.

Detailed explanation-3: -Can the mole ratio from a balanced chemical equation be interpreted as a ratio of masses? No, the ratios are not the same.

Detailed explanation-4: -A mole of any substance contains Avogadro’s number (6.02 × 1023) of atoms. To convert the number of atoms to number of moles we need to use the conversion factor: number of atoms x 1 mole / 6.023 x 1023 atoms. In other words, divide the number of atoms by 6.023 x 1023 to get the number of moles.

Detailed explanation-5: -The mole ratio may be determined by examining the coefficients in front of formulas in a balanced chemical equation. Also known as: The mole ratio is also called the mole-to-mole ratio.
