Calculate how many yottabytes (1 YB =1024 B) is required to record an object of mass 200 g? Use Avogadro’s constant of 6x1023 atoms/mol. Assume an average molecular mass of 11.3 g/mol and that 100 bits it required to store the position of each atom. NB: Remember that 11.3 grams of the object will have 6x1023 atoms, So work out how many atoms you have. Don't forget there are 8 bits in a byte. It took 10,000 YB to store a decent sized human.
