Solvent
The part of the solution that does the dissolving
Concentration
The amount of solute in a solvent or solution
Molecular
A chemical formula shows the actual amount of element
Emperical
This chemical formula shows the simplified chemical compound
Solute
The part of a solution that dissolves
Molarity
Moles of solute/liters of solution
1) find the molarity
2) Calculate moles and grams
Dilution
Makes a solution less constant
M*V=M*V
Percent by mass
Mass solute/Mass solution x 100
Percent by volume
Volume solute/ Volume solution x 100
Percent composition
The % by mass of each element in a compound
%=part/total x 100
Empirical formula
A chemical formula in lowes form
1) find the element of mole
2) Divide by the smallest mole to find the ratio
Molecular formula
A chemical formula that represents all formulas
1) If the empirical formula is not given calculate.
2)Find the mass of empirical
3) Find the ratio between the molar mass and molecular molar mass.
