The Mole - Molecular Formula Calculations

Question 1

empirical and molecular formula

Answer 1

• empirical: the smallest whole number ratio of the elements in a compound
• molecular formula - the actual number of atoms in a molecule; multiple of empirical formula

Question 2

molecular formula

Answer 2

• since the molecular formula is a multiple of empirical formula
• factor = molecular formula molar mass/empirical formula molar mass
