Quantitative Chemistry Flashcards
1
Q
Mass=
A
Mol x Rfm
2
Q
Particle no=
A
mol x avagadro’s constant
3
Q
Mol=
A
conc in mol/dm^3 x vol. in dm^3
4
Q
Mass (g) =
A
conc in g/dm^3 x vol. in dm^3
5
Q
Vol of gas=
A
mol of gas x 24
6
Q
Actual yield =
A
% yield x theoretical yield
7
Q
Mr of desired product=
A
% atom economy x Mr of all reactants
8
Q
Limiting Reactant
A
Balanced chemical equation
Find mols of all reactants
Divide each mols by coefficient in front of it
Smallest result=limiting
9
Q
Mol of product:
A
Mol of limiting reactant
10
Q
Balanced symbol equations:
A
Ratio of each molecule/atom’s mols to eachother
