Possible Answers:
Correct answer:
Explanation:
has a molar mass of approximately 40 g/mol, meaning that there is 0.01 mol of it in the solution. Sodium hydroxide is a strong base and completely dissociates in water. Its concentration in the solution is . This means that the concentration of ions is and . Thus, the pH of the solution is 11.
