Analytical Calculation and Random Errors Flashcards
an exact number of 6.02214076×10^23.
Avogadro’s Constant
The number of grams of that substance in 1 mole of that substance.
Molar Mass
An unchanging measure of the quantity of matter in an object.
Mass
The force of attraction between an object and its surroundings,
principally Earth. Because gravitational attraction varies with geographical location, the weight of an object depends on where you weigh it.
Weight
the SI unit for the amount of a chemical substance.
Mole
When expressed in the unit mol−1, this number (6.02214076x10^23) is called
Avogadro’s Number
The number of moles of that species that is contained in 1 L of the solution.
Molar Concentration
The total number of moles of a solute in 1 L of the solution.
Molar Analytical Concentration / Analytical Concentration
Refers to the molar concentration of a particular species in a solution at equilibrium.
Molar Equilibrium Concentration / Equilibrium Concentration
The negative logarithm (to the base 10) of the molar concentration of that species
P-value
The mass of a substance per unit volume.
Density
The ratio of the mass of a substance to the mass of an equal volume of water.
Specific gravity
The quantitative relationship among the amounts of reacting chemical species.
Stoichiometry
The simplest whole number ratio of atoms in a chemical compound.
Empirical Formula
Specifies the number of atoms in a molecule.
