The atomic mass of carbon (C) is 12.01amu and oxygen (O) is 16.00amu. Which molar mass is correct for carbon dioxide (CO₂)? * 2 points 28.01 g/mol 44.01 g/mol 192.16 g/mol 268.01 g/mol
44.01 g/mol is the correct molar mass for carbon dioxide (CO2).
To calculate the molar mass of a compound, you add up the atomic masses of all the atoms present in the compound. In this case, carbon dioxide has one carbon atom and two oxygen atoms.
Molar mass of carbon dioxide (CO2)
= (1 x atomic mass of carbon) + (2 x atomic mass of oxygen)
= (1 x 12.01) + (2 x 16.00)
= 12.01 + 32.00
= 44.01 g/mol
Therefore, the correct molar mass for carbon dioxide (CO2) is 44.01 g/mol.
