Find the pressure exerted by `6xx10^(23)` hydrogen molecules which will strike per second a wall of area `10^(-4) km^(2)` at `60^(@)` with normal.The mass ofhydrogen molecules and speed are `3.32xx10^(-27)` kg and `10^(-27)` kg and `10^(3) m//s` respectively.

The mass of a molecule of hydrogen is 3.332xx10^(-27) kg. Find the mass of 1 kg mol of hydrogen gas.

The mass of a hydrogen molecule is 3.32xx10^(-27) kg. If 10^(23) hydrogen molecules strike, per second, a fixed wall of area 2 cm^(2) at an angle of 45^(@) to the normal, and rebound elastically with a speed of 10^(3) m/s, then the pressure on the wall is nearly

Calculate the average momentum of a hydrogen molecule at 20^(@)C . Boltzmann constant =1.38xx10^(-23) JK^(-1) and mass of a hydrogen molecule =3.2xx10^(-27)kg .
