How many moles of c are in 440 mg of co2?

The formula of number of moles is:

    -(1)

Mass of = 440 mg  (given)

Since, 1 mg = 0.001 g

So, 440 mg = 0.44 g

Molar mass of =

Substituting the values in formula (1):

Number of moles of =

Since, in 1 mole of there is 1 mole of .

So, number of moles of in 0.01 mole of is 0.01 mole.

Hence, the number of moles of in 440 mg of is 0.01 mole.
