Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Law of definite proportions states that equal volumes of all gases under similar conditions of pressure and temperature contain equal number of molecules.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Avogadro’s law states that, “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules". For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

Detailed explanation-2: -The statement, “Equal volumes of different gases under similar conditions of temperature and pressure contain equal number of atoms.” is false.

Detailed explanation-3: -Avogadro’s Hypothesis In 1811 Avogadro hypothesized that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.
