A chemistry graduate student is given 250. mL of a 1.20 M pyridine (C3H3N) solution. Pyridine is a weak base with Kg = 1.7x10-9. what mass of CH3NHBr should the student dissolve in the CzHN solution to turn it into a buffer with pH = 5.41?
You may assume that the volume of the solution doesn't change when the CH_NHBr is dissolved in it. Be sure your answer has a unit symbol, and round it to
2 significant digits.

sry but any answer choices

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
