Title: Radioactivity - Chemical kinetics
Post by: xstrae on April 11, 2007, 09:56:19 AM

Hi,

Ten gram atoms of an alpha-active radioisotope are disintegrating in a sealed container. In one hour the helium gas collected at S.T.P is 11.2 cm³. Calculate the half life of the radio isotope.

Can someone please tell me how to do this problem? Thanks.

Unless I am missing something there is not enough data.
