When a nucleus has to many protons, it can absorb an electron and create

It would create a neutron. Because a proton+electron= and nuetron

Ch3cooh i think this is the answer

Moles = mass/molar mass the molar mass of c20 = 12.011*20 = 240.22 g per mole therefore, the number of moles is 20 g / 240.22 g per mol = 0.0833 moles.
