1Define 'The Mole'
The same amount of particles there are in 12.000g of a Carbon-12 Isotope
2Define 'Avogardo's number'
6.0225x10^23 molecules in a mole
3Define 'RAM' (relative atomic mass)
The weighted average mass of an atom of an element realitive to 1/12 the mass of an Carbon-12 Isotope
4Define 'RMM' (realtive molecular mass)
The combined weighted average mass of all the constituent atoms of each element of a compound realtive to 1/12 of the mass of a Carbon-12 isotope
5What is the Old equation to find out Volume from Moles and the conditions you need for it to be used
Moles = Volume / 24 [only working at 20deg C and 1ATM]
6What is the formula relating Concentration, Mr and mass concentration
Conc = g/dm^3 / Mr
7What is the equation linking Moles, Volume and Concentration and the units needed
Moles = Conc x Vol
Conc in mol/dm^3
Vol in dm^3
8What is another word for Concentration?
Molarity
9What is the formula for Atom economy and the additional A-level knowlege needed
Atom economy = Useful product total mass / Total mass of all products x 100
[You will have to figure out the useful product yourself]
10What is the definition of emperical formula?
The simplist whole number ratio of elements present in one molecule or formula unit of the compound
11What is the formula to use for titration?
Volume1 x Conc1 = Volume2 + Conc2
12What is titration used for?
To find the amount of acid/ alkali present in a solution
13How do you work out emperical formula
-Find the moles of each side
-Find a whole number ratio for both sides using the moles
