Calculating the composition of a buffer of a given pH A chemistry graduate student Is given 100. mL of a 0.7OM dlethylamine ((C,H) NH) solution. Dlethylamine is a weak base with K,=1.3× 10. What -3 9. mass of (C,H.) NH,Br should the student dissolve In the (C,H,) NH solutlon to turn it Into a buffer with pH =10.627 2 You may assume that the volume of the solutlon doesn't change when the (C,H,) NH,Br Is dissolved In It.
