To change any three variable equation A= B × C B= A ÷ C C = A ÷ B
Density = D = m ÷ v
Final volume – original volume V = Vf – V0 Water Displacement Final volume – original volume V = Vf – V0

Speed Distance ÷ Time
Acceleration Speed ÷ Time
Force Mass x Acceleration
Electricity V = I x R R series = R1 + R2 + … 1/R parallel = 1/R1 + 1/R2 + … I = charge / time
Parts of the atom Protons = atomic number Electrons = atomic number – charge Neutrons = Atomic Mass – protons
Moles Avogadro’s number = NA = 6.022 x 10 23
(mass of part ÷ mass of the whole) × 100 Percent Composition (mass of part ÷ mass of the whole) × 100
Molality = moles solute ÷ kg solvent Solutions Molality = moles solute ÷ kg solvent
