Calculators are usually required for these sorts of problems. The question doesn't give any information about CH3NH2+ and I don't see it in the book's appendix, So something-NH2 gets protonated to something-NH3+. The pH scale (pH) is a numeric scale used to define how acidic or basic an aqueous solution is.
