[so it dosent get mixed up with Co which is cobalt ]

anonymous · Answer

okay

unklerhaukus · Answer

if you look at a periodic table , it should have the atomic mass of Carbon , and the atomic mass of Oxygen,

unklerhaukus · Answer

the mass of a molecule is the sum of the atomic masses , multiplied by the number of time they occur in the molecule

unklerhaukus · Answer

di you find the atomic mass of Carbon?

unklerhaukus · Answer

hopefully you found 
the atomic mass of Carbon is about 12 grams/atom
and
the atomic mass of Oxygen is about 16 grams/atom

CO_2 has one carbon and two oxygens so the mass of one molecule of CO_2 is 

12 g/atom  + 2 × 16 / atom 

which is equal to about       44 grams/ molecule
