What is a reactant?
The substances that go into the reaction
What is a product?
The substances that are made in the reaction
What is the conservation of mass?
The total mass at the beginning of the reaction = the total mass at the end of the reaction (mass includes gases)
What is the percentage by mass equation?
(Relative atomic mass of specific element/Relative formula mass(all elements)) x 100
What is the concentration equation?
Concentration = Mass(g) / Volume(dm^3)
How do you convert cm into dm?
Cm / 1000 = dm
What is Avogadro's constant?
6.02 x 10^25
What is the mass equation?
Mass = relative formula mass x number of moles
How do you find out the number of moles?
Mass you are given / Relative atomic mass
