New cards

Moles

moles = mass / relative formula mass

2
New cards

Relative formula mass

relative formula mass = sum of relative atomic masses

3
New cards

Concentration

concentration = moles / volume

4
New cards

Molar gas volume

1 mole gas = 24 dm³ = 24000 cm³

5
New cards

Gas moles

moles = gas volume (dm³) / 24

6
New cards

Percentage yield

percentage yield = (actual yield / theoretical yield) × 100

7
New cards

Molecular formula

molecular formula = empirical formula × (relative molecular mass / empirical formula mass)

8
New cards

Relative atomic mass

relative atomic mass = (sum of isotopic mass × abundance) / 100

Enthalpy change

enthalpy change = products energy − reactants energy
