First, we need to convert the given number of molecules to moles:
1.00 x 10²² molecules CO₂ x (1 mole CO₂/6.022 x 10²³ molecules CO₂) = 0.0166 moles CO₂

Next, we can use the formula:
mass = moles x molar mass

The molar mass of CO₂ is 44.01 g/mol, so:
mass = 0.0166 moles CO₂ x 44.01 g/mol = 0.731 g CO₂

Therefore, the best choice is C.
