Question

What mass of protons would be required to just neutralize the charge of 1.5 g of electrons?

my teacher said .0015kg times 1e-/.00091e-27kg times 1pt/1e- times 1.67262e-27 over 1 p

Answer 1

That is what I would do also. But I think you ought to know why that is the method.

figure number electrons in 1.5g:
number electrons: .0015kg/9.11E-31

now figure the mass of the same number of protons:
1.67E-27kg*(.0015/9.11E-31)

Answer 2

do i add the e-27 and e-31. i forget

Answer 3

a^b/a^c= a^(b-c)

Answer 4

what? sry im not getting this...

Answer 5

so i got 8.087535951e20 kg. my anser is suppose to be in grams so would it be 8087.535951e17?

does this sound right/what u got?

thanks
