When cl2 gas is added to water during the disinfection of drinking water, it hydrolyzes with the water to form hocl. the disinfection power of the acid hocl is 88 times better than its conjugate base, ocl-. the pka for hocl is 7.5. (a) what % of the total disinfection power (i. e., hocl + ocl-) exists in the acid form at a ph = 6? (b) at ph = 7? (by "percentage of disinfection power" mz means  expressed as a percent.) 97% and 76%

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

i think   the answer is c hope i'm right
