Question

Sucralfate (molecular weight: 2087g/mol) is a major component of Carafate® which is prescribed for the treatment of gastrointestinal ulcers. The recommended dose for a duodenal ulcer is 1 g taken orally in 10 mL (2 teaspoons) of a solution four times a day. Calculate the molarity of the solution.

(A) 0.0005 M
(B) 0.048 M
(C) 0.02087 M
(D) 0.010 M

Answer 1

Answer:

The molarity of the solution is 0.048 M (option B)

Explanation:

Step 1: Data given

Sucralfate has a molar mass of 2087 g/mole

mass = 1g

volume = 10 mL

Step 2: Calculate moles of sucralfate

Number of moles = mass of sucralfate / Molar mass of sucralfate

Number of moles = 1 g / 2087 g/mole = 4.79 * 10^-4 moles

Step 3: Calculate molarity

Molarity = Number of moles / volume

Molarity = (4.79 * 10^-4 moles) / (10 *10^-3 L)

Molarity = 0.0479 M  ≈ 0.048 M

The molarity of the solution is 0.048 M (option B)
