Answer:
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 = \rm \dfrac{weight}{molecular\;weight}
molecularweight
weight
The molecular weight of carbon dioxide has been 44 grams/mol.
The given moles of carbon dioxide = 3.45 moles.
3.45 mol = \rm \dfrac{weight}{44\;g/mol}
44g/mol
weight
Weight of carbon dioxide = 3.45 \times× 44 grams
Weight of carbon dioxide = 151.8 grams.
The weight of 3.45 moles of carbon dioxide has been 151.8 grams.
