I have 4 decks of cards, then how many cards do I have in the diamond suit.

Explanation:

Well clearly, I have #4xx13# cards in the diamond suit.

You propose #68.5*mol# of #P_4O_10#, and clearly I have #4xx68.5*mol# of #"phosphorus atoms"#.

And this has a precise numerical value,

I,e, #4xx68.5*molxx6.022xx10^23*mol^-1=1.65*10^26# #"phosphorus atoms".#
