#3:8#

Mass of #C# in #CO_2# is #12# and mass of #O_2# in #CO_2# is #2*16=32#

So,the ratio of their mass is #12:32=3:8#

#3:8#

In #1# mole of #CO_2#, there is #1# mole of carbon and #2# moles of oxygen.

When we look on the periodic table, this tells us that there's #"12.01 g"# of carbon and #2xx16.00="32.00 g"#

This means that the ratio of the masses of carbon to oxygen is this:

#12.01 : 32.00#
#"12.01/12.01 : 32.00/12.01"#
#1:2.66#
#3:8#
