## Mole Calculation - **No. of mole of(x) = Given mass of (x)/ Molar mass of (x)** - **No. of mole particle = Given no. of particles (atoms/ions/molecules) of x / NA** ### Molar Volume (only valid for gasses) - **At const (T)(P), vol. of mole of any gas is molar volume of gas **. | Temp | Pre...

## Mole Calculation - **No. of mole of(x) = Given mass of (x)/ Molar mass of (x)** - **No. of mole particle = Given no. of particles (atoms/ions/molecules) of x / NA** ### Molar Volume (only valid for gasses) - **At const (T)(P), vol. of mole of any gas is molar volume of gas **. | Temp | Pressure | Molar Mass | |---|---|---| | 273 K | 1 atm | 22.4 L | For calculations, agar kach or mention ha | | 273 K | 1 bar | 22.7 L | (STP)| | 298 K | 1 bar | 24.7 L | (SATP)| then use jo diya hai | - 273K and 1 atm pressure, then vol. of 1 mole **of N2/ CH4/ SO2/ PH3(22.4L) Not dependent on atomicity**. ### Q. Molar vol. of gas at constant (T)(P) is independent of: **Ans.** - Nature of gas. - Atomicity of gas - Molar mass of gas.
