Methylamine, CH3NH2, is a weak base and one of several substances that give herring brine its pungent odor. In .100 M CH3NH2, only 6.4 percent of the base has undergone ionization. What are Kb and pKb of methylamine

is 0.000438 and is 3.36

Explanation:

Methylamine is a monoprotic base.

For a monoprotic base,

where, c is concentration of base in molarity and a is it's degree ionization

Here and c = 0.100 M

So,

We know,

Hence,

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
