• Relative Formula Mass Calculation: Calculating the Mr involves adding the Ar of all atoms in a compound's molecular formula
• Limiting Reactants and Moles Calculation: Understanding balanced equations, molar ratios, and how limiting reactants affect product mass and amount is crucial
• Moles and Mass: Avogadro's constant is important in understanding the amount of a substance and how to calculate moles in a given sample
• Conservation of Mass: No atoms are created or destroyed in chemical reactions, and the mass of substances, including gases, must be considered
• Calculating Mass in Reactions: A systematic approach involving balanced equations and moles is essential for determining the mass of unknown substances
