Achamber containijng a gas was evacuated till the vacuum attained was `10^(-14)` m of Hg. If the temperature of the chamber was `30^(@)C,` the number of molecules that remains in it per cubic metre is

A chamber containing a gas was evacuated till the vacuum attained was 10^(-14) m of Hg. If the temperature of the chamber was 30^(@)C, the number of molecules that remains in it per cubic metre is

In a very good vacuum system in the laboratory, the vacuum attained was 10^-13 atm . If the temperature of the system was 300 K , the number of molecules present in a volume of 1 cm^3 is.

In a very good vacuum system in the laboratory, the vacuum attained was 10^-13 atm . If the temperature of the system was 300 K , the number of molecules present in a volume of 1 cm^3 is.

A discharge tube of 2L capacity containing hydrogen gas was evacuated till the pressure inside is 1xx10^(-5)atm . If the tube is maintained at a temperature of 27^(@)C , calculate the number of hydrogen molecules still present in the tube.

When the temperature of a gas is increased at constant pressure, the number of molecules per c.c.

A discharge tube of 2 litre capacity containing hydrogen gas was evacuated till the pressure inside is 1 xx 10^(-5) atm. If the tube is maintained at a temperature of 27^@C , calculate the number of hydrogen molecules still present in the tube.

A discharge tube containing nitrogen gas at 25^(@)C in evacuated till the pressure is 2xx10^(-2) mm. If the volume of discharge tube is 2 litre. Calculate the number of nitrogen molecules still present in the tube (R=0*0821 L "atm mol"^(-1)K^(-1))

A glass tube of volume 112ml. containing a gas is partially evacuated till the pressure in it drops to 3.8 xx 10^(-5) torr at 0^@C . The number of molecules of the gas remaining in the tube is

The pressure inside an electric bulb is 10^(-3)mm of Hg at a temperature of 25^(@)C . If the volume of the bulb is 10^(-4)m^(3) , find the number of molecules contained in it.
