Chapter 4 Flashcards
An invariant measure of the quantity of matter in an object
Mass
the force of attraction between an object and its surroundings, principally the earth.
Weight
TRUE OR FALSE:
Gravitational attraction varies with geographical location, the weight of an object depends
on where you weigh it.
TRUE
It is the SI unit for the amount of a chemical substance.
mole
Abbreviated as mol
mole
The substance is the mass in
grams of 1 mole of that substance.
molar mass M
It has a chemical species is
6.022 3 1023 atoms, molecules, ions,
electrons, ion pairs, or subatomic
particles
mole
TRUE OR FALSE:
the millimole is 1/1000 of a mole, and the mass in grams of a millimole. However, the millimolar mass (mM), is 1/100 of the molar mass
FALSE
The millimolar mass is also 1/1000 of the molar mass
What is the unit of molar concentration
molar/M
It is the total number of moles of a solute, regardless of its chemical state, in 1 L
of solution.
Molar Analytical Concentration
It describes how a solution of
a given concentration can be prepared.
Molar analytical concentration
It is the molar concentration of a particular species in a solution.
Molar equilibrium concentration OR equilibrium concentration
TRUE OR FALSE:
Equilibrium molar concentrations are usually symbolized by placing square brackets around the chemical formula for the species
TRUE
It is the negative logarithm (to the base 10) of the molar concentration of that specie
p-value/p-function
It expresses the mass of a substance per unit volume. In SI units
Density
