For this case we have that, according to the periodic table, the atomic mass of the Carbon is [tex]12 \frac {g} {mol}[/tex] and that of the Oxygen is[tex]16 \frac {g} {mol}.[/tex]

By definition, the number of moles is given by:

[tex]n = \frac {M} {MM}[/tex]

Where:

M: It's the mass

MM: It's the molar mass

n: It is the number of moles

10 milligrams equals to 0.01 grams

[tex]n = \frac {0.01} {12 + 16} = \frac {0.01} {28} = 0.000357[/tex]
