a) If the average molecular mass of compounds in food is 47.5, how many molecules are there in 1.00 kg of food?
(b) How many ion pairs are created in 1.00 kg of food, if it is exposed to 100000 rad and it takes 27.5 eV to create an ion pair?
(c) Find the ratio of ion pairs to molecules.
(d) If these ion pairs recombine into a uniform distribution of 2000 new compounds, how many parts per billion is each?
