Dear sir,
I was facing problems in this question.
Calculate the total number of oxygen atoms present in 1.80g of glucose c6h12o6.
Sir you just answered my question and it was 6.022*10^22
But I was just curious to know how we would solve the question if the question asked us to find the no of oxygen molecules.
Will it be 6.023*10^21*3 ?
Thanks a lot!

							Hello Jai,I understand your doubt.The question would never ask you about the no. of oxygen molecules because it is wrong to say it.A molecule is as a whole which is of glucose. 1 molecule of glucose has 6 atoms of oxygen. We cant say 3 molecules of oxygen..Hope you understand.Thanks
