A 0.377-g sample of NaOH pellets (molar mass = 40.00 g/mol) is added to enough water to make 250.0 mL of solution. The pH of this solution is: Select one: a. 11.974 b. 12.576 c. 0.424 d. 1.424
2. Show all work (2 pts), units on every number that has units (1 pt), and the correct answer (2 pt) A relatively old container of NaOH (MW: 39.997 g/mol) pellets is used to make a -0.1 M solution. 2.00 g of the solid NaOH is weighed out, dissolved into water and diluted to a total solution volume of 500.0 mL. The NaOH solution is standardized using KHP (204.22 g/mol). It takes 15.90 mL of the NaOH solution to titrate...
