A black dot used as a full stop at the end of a sentence has a mass of about one attogram. Assuming that the dot is made up of carbon, calculate the approximate number of carbon atoms presents in the dot?  


Correct option is


ass of c carbon in the atom =1 attogram = 10–18 g

Gram atomic mass of carbon = 12 g

i.e., 12 g of carbon contain  atoms of carbon
