44

#### Explanation:

Atomic mass is very simple to calculate.
Since carbon dioxide has the structure $C {O}_{2}$
There is one carbon and 2 oxygen
so you look to the periodic table to find the atomic mass, which is located under the symbol and name of the element on the periodic table.
Carbon atomic mass of 12 amu
Oxygen atomic mass of 16 amu

since there is 1 carbon and 2 oxygen you calculate it as follows:

1(12)+2(16)=44
