Which would have a greater molar mass, carbon monoxide or carbon dioxide? why?

Carbon dioxide has a greater molar mass.

Explanation:

This is because carbon dioxide has 2 oxygen atoms increaseing the molar mass and carbon monoxide has only 1.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
