Final answer:
The molar mass of carbon monoxide (CO) is calculated by adding the molar masses of carbon (12.011 g/mol) and oxygen (16.00 g/mol), resulting in 28.011 g/mol.
Step-by-step explanation:
The molar mass of carbon monoxide (CO) can be calculated by adding together the molar masses of carbon (C) and oxygen (O). The periodic table lists the atomic mass of carbon as 12.011 atomic mass units (amu), which is equivalent to a molar mass of 12.011 grams per mole (g/mol) for carbon considering the number of atoms in a mole is defined by Avogadro's number (6.022 × 1023). The atomic mass of oxygen is approximately 16.00 amu, so its molar mass is 16.00 g/mol. Carbon monoxide contains one atom of carbon and one atom of oxygen, so its molar mass is the sum of the mass of one mole of carbon plus the mass of one mole of oxygen.
To find the molar mass of CO, we use the following calculation: 12.011 g/mol (for C) + 16.00 g/mol (for O) = 28.011 g/mol (for CO).
Therefore, the molar mass of carbon monoxide is 28.011 grams per mole.
