Atomic mass: the mass of an atom of a chemical element expressed in atomic mass units; approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes
Molar mass: a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance
Mole: the amount of a substance contained in 6.02 x 10²³ particles of that substance
Percent composition: the percent by mass of each element present in a compound
Empirical formula: a formula giving the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms
Molecular formula: a formula giving the number of atoms …show more content…
Avagadro’s Number: the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance
Mole-mole problem: in this problem, the solution procedure used involves making two ratios and setting them equal to each other
Volume-volume problem: concerns only the gaseous compounds of a reaction
Mass-mass problem: you are given the mass of a compound in the problem and asked to find the mass of another compound
Limiting reactant: a chemical reaction is the substance that is totally consumed when the chemical reaction is complete
Expected yield: the quantity of a product obtained from the complete conversion of the limiting reactant in a chemical reaction, based on ideal conditions
Actual yield: the amount actually produced of a product is the actual yield
Percent yield: a measure of the efficiency of a chemical reaction
Universal gas constant: a physical constant which is featured in many fundamental equations in the physical sciences, such as the ideal gas law and the Nernst equation
Ideal Gas Law: physical law describing the relationship of the measurable properties of an ideal gas, where P (pressure) × V (volume) = n (number of moles) × R (the gas constant) × T (temperature in
