The relative atomic masses of all atoms in a molecular formula added together. 1 of 17 What is the mole? An amount of a substance. 2 of 17 What is avogadro's constant? 6.02 * 10 (to the power of 23) 3 of 17 Number of moles = mass (g) / formula mass 4 of 17 Mass = formula mass * moles 5 of 17 Formula mass = mass (g) / moles 6 of 17 What is the conservation of mass? The idea mass cannot be created or destroyed. 7 of 17 Why could mass increase or decrease? The is a gas in the reaction that can escape or drawn in from surroundings. 8 of 17 Can moles calculate masses in reactions? Yes 9 of 17 Can you balance equations using reacting masses? Yes 10 of 17 What happens to a reaction when one reactant is used up? The reaction stops. 11 of 17 The amount of product depends on... The limiting reactant. 12 of 17 What is concentration? A measure of how crowded things are. 13 of 17 What is concentration measured in? g/dm (cubed) 14 of 17 Concentration = mass of solute (g) / volume of solvent (dm cubed) 15 of 17 Mass = concentration * volume 16 of 17 Volume = mass / concentraion 17 of 17
