Give relation between mass volume of gas. |
|
Answer» SOLUTION :In 1811 Italian scientist Amedeo Avogadro tried to combine conclusions of Dalton.s atomic theory and Gay Lussac.s law of combining volumes which is now known as Avogadro law. Avogadro.s Law : It states that equal volumes of all gases under the same conditions of temperature and pressure CONTAIN equal number of molecules. Mathematically Formula : According to Avogadro.s Law as the temperature and pressure remain constant, the volume depends UPON number of molecules of the gas or in other words amount of the gas. `V prop n` (constant T and p).....(EQ. -i) where, n = The number of MOLES of the gas `therefore V=k_(4)n ""`.....(Eq. -ii) Molar volume at STP = 22.7 L Atoms in one mole `= 6.022xx10^(23)` The relation of volume and density of gas can be obtained by `M = k_(4)d`. |
