To the nearest order of magnitude, how many moles of atoms are in a large domestic cat? The masses of a hydrogen atome, and oxygen atom, and a carbon atome are1.0u, 16 u, and 12 u, respectively. (hint: Cats are sometimes known to kill a mole.)

A mole of water molecules is about 36 grams, so if you approximate a cat as 8 kilograms of water, it's about 220 moles of water molecules. If you really want to count moles of atoms instead of moles of molecules, that'd be about 660.

Use Avagadro's number. Knowing that you have 6.02 x 10 ^23 atoms/mole: Just multiply to get your answer. 1.25 moles * 6.02 x 10^23 =7.53 x 10^23

Well, obviously, it depends on how many moles the cat actually eats. Since cats are known to bring animals home as "presents" for their owners, I'd say a cat might contain a fourth of a mole at best. That's 1.505*10^23.

The cat is a solid hydrogen atom. That is mixed with a little 7.365482*254 part oxygen. Duh
