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 molar relationship between the relative quantities of substance taking part in the reaction. (13)
  • The number of atoms per mole of the carbon-12 isotope (6.02x10^23 mol^-1). (3, 8, 8)
  • THe quantity whose unit is the mole. Chemists use 'amount of substance' as a means of counting atoms. (6, 2, 9)
  • The simplest whole-number ratio of atoms of each element present in a compound. (9, 7)
  • The weighted mean mass of a formula unit compared with one-twelfth of the mass of an atom of carbon-12. (8, 7, 4)
  • The weighted mean mass of an atom of an element compared with one-twelfth of the mass oof an atom of carbon-12 (8, 6, 4)
