A certain container has `5 xx 10^(23)` molecules of a gas `A` at a pressure of 900 torr By a photo -chemical combination allowing light to fall on the molecules the pressure drops to 500 torr due to dimerization If the temperature and volume remain the same how many monomer dimer and total molecules are present after exposure to light ? .

Answer

`(5)/(9) xx 10^(23) ,(20)/(9) xx 10^(23), (25)/(9) xx 10^(23)` .
