Answer:

There will be 30 g of carbon and 80 g of oxygen.

Explanation:

If you had 3 g of #"C"# and 8 g of #"O"#, you would have 11 g of #"CO"_2#.

∴ In 110 g of #"CO"_2#, there would be

#"Mass of C" = 110 color(red)(cancel(color(black)("g CO"_2))) × "3 g C"/(11 color(red)(cancel(color(black)("g CO"_2)))) = "30 g C"#

#"Mass of O" = 110 color(red)(cancel(color(black)("g CO"_2))) × "8 g C"/(11 color(red)(cancel(color(black)("g CO"_2)))) = "80 g O"#
