What mass of protons would be required to just neutralize the charge of 1.7 g of electrons?

Question

I thought it was simple because 1 proton maxes out 1 electron but my teacher started talking abou this complicated way of doing it and i didn't get it :(

can someone show me how to do this problem? Thanks

Answer 1

you don't have one electron.

Number of electrons=mass/massoneelectron
= .0017kg/9.11E-31kg

Now find the mass of an equal number of protons.

Answer 2

i got 1.1e54 for the mass of protons required but it said it was wrong
