“Mole…mole…mole…”. Not the kind on your face…. What you know…. What an atomic mass unit ( amu ) is What the formula mass of a given molecule is How to convert from atoms to amu With elements With compounds . Objectives. SWBAT define a mole .
Measurements of CO 2 Molar Mixing Ratio by Infrared Absorption Spectroscopy C, mole fraction ( μ mole mole -1 = ppm) LI-COR analyzers measure absorbance at 4.26 μ m V = kA (voltage proportional to absorbance) ρ c = P c /RT = CP/RT (molar density of absorber)
Stoichiometry Mole-Mole Problems. Mr. Shields Regents Chemistry Unit 11 L03. Once we’ve balanced a chemical equation What other information does if provide? For example: What information does the following give us? N 2 H 4 (g) + 2H 2 O 2 (l) N 2 (g) + 4H 2 0 (l).
Mole. The mass of a single atom is too small to measure on a balance. E.g. mass of a hydrogen atom = 1.673x10 -24 g An analytical balance can measure up to 4 decimals. To measure atoms in the real world we need a huge number of atoms. That huge # we define as a mole.
