How was rutherford’s gold foil experiment inconsistent with the plum pudding model of the atom?
a.
the model could not explain how alpha particles could be deflected at large angles.
b.
the model could not explain how alpha particles could penetrate the atoms.
c.
the model could not explain why the electrons in the atom would be evenly spaced.
d.
the model could not explain why alpha particles passed through the nucleus without any deflection.

d

explanation:

rutherford's experiment showed that the atom does not contain a uniform distribution of charge.

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

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

will have a gram-molecular weight of 352g.
