Document Summary
1 mole = 6. 02 x 1023 particles (atoms, ions, molecules) 3. 01 x 1024 c atoms x ________1mol_________ = 5. 00 mol c. Conversion factors: 6. 02 x 1023 particles or 1 mol__________ 6. 02 x 1023 particles: conversions between # of particles and moles. Type 1: given the number of particles, determine the number of moles that are present. Type 2: given the number of moles, determine the number of particles that would be present. 0. 75 mol co2 x 6. 02 x 1023 molecules co2 = 4. 5 x 1023 molecules co2. Conversion factors: x g or 1 mol__: 6 mol billfold , how many hydrogen atoms are present in 2. 6 moles of ch4, conversions between mass of a substance and moles of. Type 3: given the number of moles of a substance, determine how many grams of that substance would be present. Molecular mass of no2 = 1 n x 14. 0 amu = 14. 0 amu. 2 o x 16. 0 amu = 32. 0 amu.
