# How many moles are equal to 2.69 * 10^78 atoms of sulfur?

$4.47 \times {10}^{54}$ moles

#### Explanation:

How many dozens is 72? you just need to divide 72 by 12.

With mols it is exactly the same thing.
1 mol is approximately $6.022 \times {10}^{23}$, so you must divide the given number by $6.022 \times {10}^{23}$:

$\frac{2.69 \times {10}^{78}}{6.022 \times {10}^{23}} = 4.47 \times {10}^{54}$

Since the molar mass of Sulfur is about 32.06 g/mol you will get:

$4.47 \times {10}^{54} \times 32.06 \times {10}^{- 3} = 1.43 \times {10}^{53} k g$

This number is extraordinarly huge. It is comparable with the mass of the whole Universe, which it's taken as being at least ${10}^{53} k g$
