44 atomic mass units (amu's) = 44 grams/mole

#### Explanation:

In chemical stoichiometry the mole is defined as the mass of substance containing 1 Avogadro's Number $\left({N}_{o}\right)$ of particles. 1${N}_{o} = 6.023 \times {10}^{23} u n i t s$. For $C {O}_{2}$ the weight (in grams) containing 1 ${N}_{o} o f C {O}_{2}$ molecules = 44 grams (to 2 sig figs).
