Draw an X on the time axis to show when the system first reached equilibrium. Describe the change that was made to the system at time t1. After the change was made at time t1, the partial pressure of SO3 (g) increased while the partial pressure of O2 (g) decreased. Explain this observation. Write the expression for the equilibrium constant, Kp, for the reaction. Determine the value of Kp 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.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
