01given
Given properties to classify:
1. Volume
2. Molar heat capacity
3. Molarity
4. Ecell0
5. Gibbs free energy change (ΔG)
6. Molar mass
7. Mole
02find
Total count of intensive properties among the given set.
03strategise
An intensive property does not depend on the quantity of matter in the system. An extensive property depends on the size or mass of the system.
The ratio of two extensive properties gives an intensive property. Molar quantities and concentrations are examples of this rule.
Standard electrode potential (Ecell0) is also intensive. It is the ratio of extensive ΔG0 to extensive nF.
04execute
Classify each property:
- Volume: Extensive (depends on amount)
- Molar heat capacity: Intensive (heat capacity per mole)
- Molarity: Intensive (moles per unit volume, ratio of two extensive quantities)
- Ecell0: Intensive (electrode potential does not depend on system size)
- Gibbs free energy change (ΔG): Extensive (scales directly with mass/moles)
- Molar mass: Intensive (mass per mole, characteristic of a substance)
- Mole: Extensive (direct measure of quantity of matter)
Intensive properties = {Molar heat capacity, Molarity, Ecell0, Molar mass}.
Total count = 4.
✓verify
Out of 7 total properties, 3 are extensive (Volume, ΔG, Mole) and 4 are intensive (Molar heat capacity, Molarity, Ecell0, Molar mass). Total = 3 + 4 = 7. Consistent.

Students also ask
Why is molar mass intensive when mass is extensive?
Mass depends on the quantity of substance present. Molar mass is the mass per one mole of the substance. It is the ratio of two extensive properties: Mass / Mole. This ratio is independent of system size, so it is an intensive property.
Why is E0 cell intensive when Delta G is extensive?
ΔG∘=−nFEcell∘. Here ΔG∘ and n both scale with the size of the reaction (extensive), so their ratio Ecell∘=−ΔG∘/(nF) is independent of system size, making Ecell0 an intensive property.
