Clues

  • a solution of a known concentration. Standard solutions are normally used in titrations to determine unknown information about another substance. (8, 8)
  • The actual number of atoms of each element in a molecule. (9, 7)
  • The amount of solute, in mol, dissolved per 1 dm3 of solution. (13)
  • The mass of an atom of an isotope compared with one-twelfth of the mean mass of an atom of carbon-12. (8, 8, 4)
  • The mass per mole of a substance. The units of molar mass are g mol-1. (5, 4)
  • the molar relationship between the relative quantities of substance taking part in the reaction. (13)
  • The number of particles in the nuclues. (4, 6)
  • The number of protons in the nucleus of an atom. (6, 6)
  • The volume per mole os a gas. The units of molar volume are dm3 mol-1. At room temperature and pressure, the molar volume is approximately 24.0dm3mol-1. (5, 6)
  • The weighted mean mass of a formula unit compared with one-twelfth of the mass of an atom of carbon-12. (8, 7, 4)
