how many electrons are in 3.70 x 10^23 atoms of carbon 13?

Answer 1

carbon 13 = 6 protons (because of its atomic number) and 7 neutrons)

since carbon 13 has 6 protons, it also has 6 electrons to counteract

(3.70 x 10^23 atoms)(6 electrons/atom)=?

Answer 2

how many neutrons are in this amount of 2.78×10^23 13^C atoms?

Answer 3

(2.78 x 10^23)(7 neutrons)=1.946 x 10^24
