but in book answers are different that's why I am asking
can u tell me the book answer
yes it is a difference between number of oxygen atom or oxygen atom as number of oxygen atom is present in a oxygen or a oxygen
in one question it was asking number of atoms so in glucose oxgen atoms are 6 it multiply it with avogadro no. so hence it find number of oxgen atom in glucose:: but in another question it was asking how many oxgen atom are present in caco3 in solution firstly it find no. of moles then multiply it by avogadro number
