SI unit for the amount of a chemical substance

mole

the mass in grams of 1 mole of that substance

molar mass

is 1/1000 of a mole, and the mass in grams of that substance

millimole

the number of mole of that species that is contained in 1 liter solution

molar concentration

total number of moles of a solute, regardless of its state in 1L of solution

molar analytical concentration

the molar concentration of particular species in a solution

molar equilibrium concentration

parts per hundred

percent concentration

used to EXPRESS the concentration of commercial aqueous reagents

weight percent

used to SPECIFY the concentration of a solution

volume percent

often used to INDICATE the composition of dilute aqueous solution of solid reagents

weight or volume percent

expresses the mass of a substance per unit volume

density

ratio of the mass of a substance to tye mass of an equal volume of water

specific gravity

the relationship among the number of moles of reactants and products

stoichiometry

gives tye SIMPLEST whole number ratio of atoms in a chemical compound

emperical formula

SPECIFIES the number of atoms in a molecule

molecular formula

samples of about the same size that are carried through an analysis in the exact same way

replicates

also called arithmetic mean or average

mean

the middle value in a set of data that has been arrange in numerical order

median

can have significand effect on the mean of tge set but has no effect on median

outlier

closeness of result to others

precision

closeness on results to the true vallue

accuracy

the difference between the measured value or true value

absolute error

often more useful quantity than the absolute error

relative error

-causes data to be scattered more or less symmetrically - affects measurement precision

random error

the collection of all measurements of interest to the experimenter

population

subset of measurements selected from the population

sample

measure of the precision of the population

population standard deviation

a measure of precision

sample standard deviation

-causes the mean of a data set to differ from accepted value - affects accuracy of results/measurement

systematic error
