The Mole
- Explain what a mole is, and convert among the number of particles, moles and mass of a compound. Determine the molar mass of an element or compound (C1/2)
STP
- Explain what STP is, and state the molar volume of a gas at STP. Calculate the moles or mass of a gas from a given volume at STP or vice versa. Explain Avogadro's hypothesis (C3)
Molecular and Empirical Formulas
- Explain the difference between empirical and molecular formulae. Determine the percent composition by mass from the formula of a compound. Determine the empirical formula for a compound from the percent composition by mass. Determine a molecular formula from the molecular mass and empirical formula. (C4)
Molarity
- Express molarity using mol/L or M, perform calculations relating mass (or moles) of solute, volume of solution, and molarity. Calculate concentrations after dilutions. (C5/6)
