Answer:

0.39

Explanation:

Recall that the moles of the elements in a compound can be found using their subscripts. #CO_2# consists of one carbon atom and two oxygen atoms; one molecule of #CO_2# = 1 atom of carbon and 2 atoms of oxygen. This is the same for moles. 1 mole of #CO_2# = 1 mole of C and 2 moles of O atoms (or 1 mole of #O_2# molecules). If we have 0.39 moles of #CO_2#, then we will also have 0.39 moles of C.
