151.8 grams bc basically all youre supposed to do is find the molar mass of CO2 which is 44 and then multiply it by 3.45. remember that finding grams is always multiplication and for moles its division

The weight of 3.45 moles of carbon dioxide has been 151.8 grams.

Moles can be calculated as the mass of solute present with respect to the molecular mass of the solute.

Moles can be expressed as:

Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]

The molecular weight of carbon dioxide has been 44 grams/mol.

The given moles of carbon dioxide = 3.45 moles.

3.45 mol = [tex]\rm \dfrac{weight}{44\;g/mol}[/tex]

Weight of carbon dioxide = 3.45 [tex]\times[/tex] 44 grams

Weight of carbon dioxide = 151.8 grams.

The weight of 3.45 moles of carbon dioxide has been 151.8 grams.
