Final answer:
The concentration of α-glucose after equilibrium is attained is equal to 1 M.
Step-by-step explanation:
When α-glucose is dissolved in water, it forms a solution. In this solution, a dynamic equilibrium is established between the dissolved glucose molecules and the undissolved glucose molecules. This means that glucose molecules continue to dissolve and precipitate at the same rate. At equilibrium, the concentration of α-glucose in the solution will be the same as the initial concentration, which is 1 M. Therefore, the concentration of α-glucose after equilibrium is attained is equal to 1 M.
