The pre-exponential factor and activation energy for the hydrolysis oft-butyl chloride are 2.1 x 10 16 s-1 and 102 kJ mo1-1, respectively. Calculate the values of tis0 t and tiH0 t at 286 K for the reaction.

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'm wiling to try and you : )
