A mole of atoms is 6.02 × 10^23 atoms. How many moles of atoms are in a domestic cat with a mass of 10 kg? Take the mass of an average atom in the cat to be 12 u. Number Units

Step 1
First, we need to convert the mass of the cat from kg to atomic mass units (u). 1 kg = 1000 g, so 10 kg = 10,000 g. 1 g = 6.022 x 10^23 u (Avogadro's number), so 10,000 g = 6.022 x 10^23 u * 10,000 = 6.022 x 10^26 u. Show more…

A mole of atoms is $6.02 \times 10^{23}$ atoms. To the nearest order of magnitude, how many moles of atoms are in a large domestic cat? The masses of a hydrogen atom, an oxygen atom, and a carbon atom are $1.0 \mathrm{u}, 16 \mathrm{u},$ and $12 \mathrm{u},$ respectively. (Hint: Cats are sometimes known to kill a mole.)
