Moles - Coggle Diagram
Moles
Moles and solutions
conc = mol / vol (dm3)
Know how to make a standard solution
See textbook page 49
Mass concentrations
Mass of a solute dissolved in 1dm3 solution
Concentrated acids = x > 10 mol dm-3
mol = vol (cm3) / 1000
Moles and gasses
Moles = volume / 24000 cm3
Moles = vol / 24 dm3
Ideal gas equation
PV = nRT
Units: P = Pa, V = m3, T = K,
m3 --> dm3 = x1000
Stoichiometry
Measures the amount of substances involved in a chemical reaction
Refers to the molar reacting quantities (how many moles of x react with y)
Equations
Giant structures
Where many atoms or ions bond in a repeating fashion
