In an experiment a spot 1.0 cm in diameter contains about 12 microleters of solution. If the Fe(NO3)3 solution contains about 6.0 g Fe3+ per liter how many nanograms of Fe3+ ions are there in a 1.0 cm diameter spot og Fe(NO3)3

The  mass of   present is  

Explanation:

From the question we are told that

   The  diameter of the spot is  

   The  volume of the  solution present is  

    The  mass of   ions in  one  liter of solution is

Generally the mass of   ions present is  v is mathematically represented as

Converting to nanograms

We have  

i think a, hope it .
