Question: A mole of elephants would weigh how much more than the moon?

Solution:

One mole of elephants contains $6.02 \times 10^{23}$ elephants.

One Asian elephant have weight about $4000\ \mathrm{kg}$.

$$6.02 \times 10^{23} \times 4000\ \mathrm{kg} = 2.41 \times 10^{27}\ \mathrm{kg}$$

Mass of the Moon is $7.32 \times 10^{22}\ \mathrm{kg}$

$$\frac{m(\text{mole of elephants})}{m(\text{Moon})} = \frac{2.41 \times 10^{27}\ \mathrm{kg}}{7.32 \times 10^{22}\ \mathrm{kg}} = 3.29 \times 10^4$$

Answer: a mole of elephants is $3.29 \times 10^4$ times much more than the Moon.
