Homework Help: Stoichiometry question

  1. Oct 29, 2012 #1
    C10H16N5O13P3 is the formula of ATP. What is the weight precentage of Nitrogen in 0.16 mol of ATP?

    Does it mean that in 0.16 mol of ATP I have 0.16 mol of N? or maybe of N5? I'm confused...

    0.16 mol is there just to confuse you. Weight percentage on element in a substance doesn't depend on the substance amount.
