12.1. Mole Ratios http://www.ck12.org
Points to Consider
In the laboratory, there is no way for a chemist to directly measure out moles of a substance. He or she, instead,
must determine amounts either by mass or by volume. Therefore, it is important to be able to perform stoichiometric
calculations with mass and volume.
- How is mass converted to moles?
- How are moles converted to mass?
- How many conversion factors are required to convert from the mass of a given substance to the mass of an
unknown substance?
