A mole is:

• The SI unit for mass

• The SI unit for the amount of a substance

• The SI unit for volume

• The SI unit for area

What converting from moles to the number of particles, moles is multiplied by:

• an equivalent value

• a conversion factor

• the number of atoms in the formula

• the mass of the substance

Which has the most particles?

• 1 mole H₂

• 1 mole Na¹⁺

• 1 mole Al(OH)₃

• These are all the same

Why is the mole used in chemistry?

• The mass of atoms is in AMUs which is too hard to convert to grams.

• A dozen is not a scientific amount.

• Chemists needed to make chemistry easier to understand.

• It makes counting large numbers of small particles easier.

How is moles abbreviated?

• M

• m

• mol

• ml

What is the mole used for? 

• To measure the amount of grams in a substance
• To measure the amount of atoms or molecules in a substance
• To measure the amount of energy in a substance
• To measure the amount of bonding in a substance
