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.

- 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

- Possibly
- Yes
- No
- Depends on the weather
