moles of an element

• What does relative atomic mass represent?

  The mass of a single atom of an element
• How is relative atomic mass calculated?

  From average masses of isotopes weighted by abundance
• Where can relative atomic masses be found?

  On the periodic table
• What does the term "mole" refer to in chemistry?

  A very large number of particles
• What is the significance of the mole in chemistry?

  It allows calculation of atoms in reactions
• How do you calculate the number of moles from mass?

  Divide mass in grams by relative atomic mass
• What is the equation for calculating the number of moles?

  Number of moles = mass / relative atomic mass
• What is the process for calculating moles from mass?

  • Identify the mass of the element in grams
  • Find the relative atomic mass from the periodic table
  • Use the formula: Number of moles = mass / relative atomic mass
