Equations Flashcards
1
Q
Moles
A
Mole=Mass / Mr
Mole = Number of particles / Avogadro constant
Moles = volume of gas / 24
n=PV/RT
2
Q
Percentage error
A
Percentage error = Difference (in Mr of attained Mr and actual Mr) / actual Mr
3
Q
Percentage uncertainty
A
Uncertainty= (0.01 x number of measurements taken) / mass of the compound being measured
4
Q
Percentage yield
A
Percentage yield = actual yield / predicted yield
5
Q
Charge density
A
Charge density = charge of the ion / ionic radius
6
Q
Volume
A
Volume = mole x 24
Volume = Mole / Concentration
V=nRT/P
7
Q
Concentration
A
Concentration = moles / Volume
Concentration = mass / volume
