1.

The number of molecules of an ideal gas in a 8.2 L container at 380 torr and 27^(@)C will be

Answer»

`6.02 XX 10^(23)`
`1.0 xx 10^(22)`
`1.0 xx 10^(23)`
`1.204xx 10^(24)`

Solution :Number of MOLECULES`= ( PV)/( RT) xx N_(0)`
`= ( 380 //760 xx 8.2)/( 0.082 xx 300) xx 6.02 xx 10^(23)`
`= 1.0 xx 10^(23)`
