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]
ANswer:
Option C
Answer:
0.000357 shows how many moles 10.0 of CO represent
