Questions and Answers

What do the chemical properties of elements depend on?

  • Their relative atomic mass and relative molecular mass
  • Their arrangement in the Periodic Table
  • Their mass number and isotopes
  • Their atomic structure and arrangement of electrons (correct)

    • How do chemists measure out an amount of a substance?

  • Using an amount in moles (correct)
  • By measuring the mass in grams only
  • By measuring the volume in dm3 of a gas only
  • By measuring the mass and volume simultaneously

    • What is the mole a useful quantity for?

  • Because it measures the volume of a gas
  • Because it determines the chemical properties of elements
  • Because it represents the mass of an element
  • Because one mole of a substance always contains the same number of entities of the substance (correct)
