Moles = mass / molar mass

#### Explanation:

Here, you are given the mass of 10.269 grams.

The molar mass can be found through the periodic table.

Molar mass:

$= \left(2 \cdot 26.98\right) + \left(32.065 \cdot 3\right) + \left(12 \cdot 15.9994\right)$

$= 182.15 g r a m s$

Moles = $\frac{10.269}{182.15} = \ast 0.06 m o \le s \ast$
