A sample of (N2H5)2C3H4O4 contains 1.084 x 1024 carbon atoms. How many moles of hydrogen atoms are there in the same sample? Avogadro’s number = 6.022 x 1023.
Answered by bobpursley
counting 10 H + 12h=22H

so it must be 22* 1.084E24/avanumber

I believe Bob P counted the H atoms wrong. It's 10 from the (N2H5)2 and 4 more from the other part of the formula for a total of 14 and not 22.
