Gay-Lussac's Law

Gases react in simple whole-number volume ratios (constant T, P)

Avogadro's Law

Equal volumes of gases contain equal molecules (same T, P)

Molar volume at 25°C25°\text{C} and 100 kPa100 \text{ kPa}

24.79 L24.79 \text{ L}

Molar volume at 0°C0°\text{C} and 100 kPa100 \text{ kPa}

22.71 L22.71 \text{ L}

Why gases need T & P specified

Volumes highly sensitive to T and P changes

Standard pressure value

100 kPa100 \text{ kPa}

Volume ratios vs mole ratios for gases

Equal at same T and P

Examples of diatomic molecules

H2\text{H}_2, Cl2\text{Cl}_2, O2\text{O}_2

Volume ratio: H2+Cl22HCl\text{H}_2 + \text{Cl}_2 \to 2\text{HCl}
