What mass of protons would be required to just neutralize the charge of 1.5 g of electrons?
my teacher said .0015kg times 1e/.00091e27kg times 1pt/1e times 1.67262e27 over 1 p

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/9.11E31
now figure the mass of the same number of protons:
1.67E27kg*(.0015/9.11E31) 
do i add the e27 and e31. i forget

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

what? sry im not getting this...

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
