Option b. 0.048 M

Explanation:

We have the molecular weight and the mass, from sulcralfate.

Let's convert the mass in g, to moles

1 g. 1 mol / 2087 g = 4.79*10⁻⁴ moles.

Molarity is mol / L

Let's convert the volume of solution in L

10 mL. 1L/1000 mL = 0.01 L

4.79*10⁻⁴ mol / 0.01 L = 0.048 mol/L
