Question 1

stoichiometry

Answer 1

is about the relative amounts of reactants and products in a chemical reaction

Question 2

moles

Answer 2

• the SI unit of the amount of substance that contains the same number of specified entities as there are atoms of exactly 12g of carbon of the carbon isotope 12Cm
• n = mol

Question 3

molar mass

Answer 3

• the mass of 1 mole of a specified entity
• M = g.mol-1

Question 4

limiting reagent

Answer 4

the reactant that is completely consumed in a chemical reaction, and therefore limits the amount of product that can be formed
