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.
