Relative Masses (Edexcel)

Foundations in AS Chemistry

AS Chemistry Bundle on Foundations in Chemistry. Suitable for AQA, OCR and Edexcel The lessons include: Lesson 1: Relative Masses 1) Define the terms relative atomic mass, relative formula mass and relative molecular mass 2) Calculate the relative formula mass and relative molecular mass of compounds and molecules Lesson 1: Relative Masses (For Edexcel) 1)To define the terms relative atomic mass and relative isotopic mass 2) To understand the terms relative formula mass and relative molecular mass of compounds and molecules 3) To calculate the relative formula mass and relative molecular mass of compounds and molecules using relative atomic mass Lesson 2: Ions and the Periodic Table 1) To predict the ionic charge of ions based on the position of the element in the periodic table 2) To recall the names of common atomic and molecular ions 3) To be able write the formula of ionic compounds Lesson 3: The Mole and The Avogadro Constant 1) Know that the Avogadro constant is the number of particles in a mole 2) Calculate the number of moles present in a given mass of an element or compound using the mole equation 3) Rearrange the mole equation to calculate either the number of moles, Mr or mass of an element or compound Lesson 4: Moles and Equations 1) Know how to balance symbol equations 2) Calculate the moles of reactants or products based on chemical equations and mole ratios 3) Calculate the masses of reactants used or products formed based on chemical equations and mole ratios Lesson 5: Ideal Gas Equation 1) Recall the ideal gas equation 2)Understand the properties of an ideal gas 3) Rearrange the ideal gas equation to determine either pressure, temperature, moles or volume Lesson 6: Empirical and Molecular Formulae 1) Understand what is meant by ‘empirical formula’ and ‘molecular formula’ 2) Calculate empirical formula from data giving composition by mass or percentage by mass 3) Calculate molecular formula from the empirical formula and relative molecular mass. Lesson 7: Percentage Yield and Atom Economy 1) Know how to balance symbol equations 2) Calculate atom economy and percentage yield from balanced symbol equations 3) Calculate the masses and moles of products or reactants from balanced symbol equations ***Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation. This is because planning your own lessons, including using your own lesson PowerPoints, is a fundamental skill of a qualified/unqualified teacher that will be assessed during the scenarios outlined above***
