Chemistry - Solutions (Concentration)
solute solvent
the number of moles of a ___ doesn't change if you add more ___ to the solution
molarity
the number of moles of solute in one liter of the solution
molality
the number of moles of solute per kilogram of solvent
mole fraction
the ratio of moles of solute to the total number of moles of solute and solvent
solvent
the substance in a solution that does the dissolving
solute
the substance in a solution that is dissolved
solute solvent volume
to make a solution... - Pour a small amount of ___ - add the ___ - Carefully fill to final ___
solute
which is the smaller amount of a solution, the solute or the solvent
solutions
Kinds of ___ include: - solid/liquid - liquid/liquid - gas/liquid - gas/solid
mol/L
M =
M2 • V2
M1 • V1 = - M is concentration - V is volume
dilution
adding water to a solution
mol of solute/Kg of solvent
m =
m
molality is represented by ___
M
molarity is represented by __ - in a numerical answer you can say 3 molar
X
mole fraction is represented by
number of moles after
number of moles before =
percent
part per 100
vol solute/vol solution • 100 (you can also use the mass of the solute instead of the volume)
percent concentration of a solution =
solution
solute + solvent
Na/Na + Nb
X =
concentration
a measure of the amount of solute dissolved in a given quantity of solvent
concentrated solution
a solution with a large amount of solute
diluted solution
a solution with a small amount of solute
