is beta active and has a short half life of 14 days. The nucleus produced is in ground state. On an average, the emitted beta particles have of the energy released in the reaction, remaining energy being carried by antineutrino. A liquid has small amount of in it and it was found that the liquid was receiving heat at a rate of about due to decay of . It is to be noted that antineutrino do not interact with matter easily and it would be safe to assume that they escape out of the container. Estimate the number of atom in the liquid.
