New cards

Mole of a Solid

Mole (n) = Mass (g) / Molar Mass (g/mol)

2
New cards

Mole of a Gas (at RTP)

Mole (n) = Volume (dm³) / Molar Volume (24 dm³/mol)

3
New cards

Mole of a Solution

Mole (n) = Concentration (mol/dm³) × Volume (dm³)

4
New cards

Volume of a Solution

Volume (dm³) =(

1000 × mole (mol/m²)) / Concentration (mol/dm³)

5
New cards

Percentage Purity

%Purity = Mass of Pure Product / Mass of Impure Product × 100

6
New cards

Percentage Yield

%Yield = Actual Mass / Predicted Mass × 100
