Options

(a) Law of gaseous volumes
(b) Avogadro’s hypothesis
(c) Berzelius hypothesis
(d) Dalton’s atomic theory

Correct Answer:

Avogadro’s hypothesis

Explanation:

Avogadro gave a hypothesis stating that the volume of gas is directly proportional to the number of molecules of gas. As one moles of substance always contains same number of molecules ie (6.022 × 10²³). So the volume is always 22.4 at NTP. NTP is normal temperature.
