it looks like I got too big numbers for the uncertainty

 

[Charles Link]

Looks like you got the calculus part correct. The numbers you entered after that are too small and not written neatly enough to be able to see them.

You seem to have crossed over terms, e.g. you have $\frac{\partial Z}{\partial A}\alpha_B$ instead of $\frac{\partial Z}{\partial A}\alpha_A$.

Oh, thank you so much I got 38.98 now for part b). I hope that this is correct.

Looks ok. Notice that the fractional uncertainty in d (1 in 14) is far higher than that in M. This means you can ignore the uncertainty in M and write down immediately that the uncertainty in g is 1 in 7 (doubled because of d²).
