Document Summary

Mole: amount of a substance that contains as many entities as there are in 12g of carbon-12; this is avogardo"s number ie. 6. 022 x 1023; exact same # of particles (anything); a specific and convenient # A mole of hydrogen is 6. 022 x 1023 atoms; a mole of chips is 6. 022 x 1023 individual chips. Atomic mass unit: one 12c atom has a mass of 12 amu therefore 1 mole of 12c weighs 12g; one. 24mg atom has a mass of 24 amu therefore 1 mole weighs 24g. The atomic mass of one individual atom or molecule is measured in amu (ex 12amu) This equation describes the relationship between pressure, volume, concentration (moles), and temperature. How many carbon atoms are in 1 mole of glucose: you have 30 moles of calcium in your body.
