Term | Definition |
A mole | the amount of particles that have their mass in grams equal to their atomic masses. 6.02x10 23 particles |
Formula mass | sum of all the masses in a formula, in amu’s |
Gram formula mass | sum of all the masses in a formula, in grams |
Molar mass | synonym of gram formula mass |
Percent composition | (mass of the part/mass of the whole cmpd) x 100 |
Percent yield | (mass you actually produced / theoretical maximum amount that could have been produced) x 100 |
Calculation average isotopic mass | multiply each isotopes mass by its abundance in decimal form. Add these to get the final average. DO NOT divide by ANYTHING at the end! |
Molecule | a group of elements with covalent bonds |
Formula units | ions, held together by ionic bonds |
Atoms | elements, not bonded to anything else |
Empirical formula | contains subscripts in the lowest possible ratio |
Molecular formula | contains subscripts not reduced to lowest ratio |
mole ratio | the coefficient ratio from a balanced equation |
stoichiometry | using mole ratio and mole conversion to predict experimental yields |
