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


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

  • science - ,

    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.

  • science - ,

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