A sample of 0.177g of an ideal gas occupies `1000cm^(3)`at STP. Caculate the rms speed of gas molecules.

The rms speed of a gas molecule is

The rms speed of a gas molecule is

One mole of an ideal gas occupies 22.4L at STP. Calculate the number of atoms present in the above sample.

An ideal gas is maintained at constant pressure. If the temperature of an ideal gas increases from 100K to 1000K then the rms speed of the gas molecules

An ideal gas is maintained at constant pressure. If the temperature of an ideal gas increase from 100K to 1000K then the rms speed of the gas molecules:

0.28 g of a gas occupies 227 mL at STP. The gas could be:
