Final answer:
No, the molar mass of water (18.016 g/mol) is not greater than that of carbon monoxide (28.01 g/mol).
Step-by-step explanation:
To determine whether the molar mass of water is greater than that of carbon monoxide, we must calculate the molar mass of each compound. The molar mass of water (H2O) is calculated as follows: (2 × 1.008 g/mol for hydrogen) + (16.00 g/mol for oxygen) = 18.016 g/mol. On the other hand, the molar mass of carbon monoxide (CO) is the sum of the atomic masses of carbon and oxygen, which are 12.01 g/mol and 16.00 g/mol respectively, amounting to 28.01 g/mol.
Comparing the two molar masses, we see that the molar mass of water is indeed less than that of carbon monoxide. Therefore, the answer to the question is b) No, the molar mass of water is not greater than that of carbon monoxide.
