This refers to your archive question in 2014 Oct 30 at 4.58 posted by Ruzzle and replied by DrBob222.

Small query on the solution , which states 1/6 of D atoms will go to form D2O18. Isn't it 2/6 since out of all 6 D atoms 2 is required to form D2O18.

Please clarify.
Regards thanks

I looked in the archive section of 2014 and was unable to find the post to which you refer. Sorry.
