6. Concentration =

  • mass of solvent (g) / volume of solute (dm squared)
  • mass of solute (kg) / volume of solvent (dm cubed)
  • mass of solute (g) / volume of solvent (dm cubed)
  • mass of solute (N) / volume of solvent (dm squared)

7. Formula mass =

  • formula mass / moles
  • mass (g) * moles
  • mass (g) / moles
  • mass (g) / formula mass

8. Mass =

  • mass * velocity
  • moles / formula mass
  • formula mass * moles
  • moles / 100

9. What is the mole?

  • I honestly don't care.
  • The amount of atoms in a mixture.
  • An amount of a substance.
  • The amount of elements in the periodic table.

10. The amount of product depends on...

  • The conservation of mass.
  • The amount of formla mass that is preggers.
  • The limiting reactant.
  • The mole.

11. Why could mass increase or decrease?

  • The is a gas in the reaction that can escape or drawn in from surroundings.
  • Someone spilt milk onto the reaction.
  • It ate too much pizza or went on a diet.

12. Can moles calculate masses in reactions?

  • Sometimes
  • Yes
  • No
  • Je ne sais pas, pourquoi

13. What is the conservation of mass?

  • The idea that mass can be created and destroyed only in metals.
  • A 3D printer.
  • The idea mass cannot be created or destroyed.
  • The idea mass can be created or destroyed.

14. What is concentration?

  • I don't know.
  • A measure of how crowded things are.
  • Another word for consevation of mass.

15. Number of moles =

  • formula mass / mass (g)
  • mass (g) / formula mass
  • mass (g) * formula mass
  • mass (g) * 100

16. What is avogadro's constant?

  • 6.03 * 10 (to the power of 23)
  • 6.23 * 10 (to the power of 23)
  • 6.02 * 10 (to the power of 23)
  • 2.06 * 10 (to the power of 23)

17. Can you balance equations using reacting masses?

  • Possibly
  • Yes
  • No
  • Depends on the weather
