In a slow reaction, heat is being evolved at a rate about 10 m W in a liquid. If the heat were being generated by the decay `of ^(32)` P, a radioactive isotope of phosphorus that has half-life of 14 days and emits only beta-particles with a mean energy of 700KeV, estimate the number `of ^(32)` P atoms in the liquid. Express your answer in form of `Axx10^(15)` and fill A in OMR sheet. Round off A to nearest integer [Take:l n`2=0.7`]
