Explanation / Answer

1) carbon atom = 6 protons

2 oxygen atoms = 8*2 = 16 protons

1 molecule of CO2 = 16 + 6 = 22 protons

1 mole = 44 grams

1 mole = 6.023 x 10^23 molecules

x grams = (1/44)* x * ( 6.023 x 10^23) * 22 = 3.011 * 10^23 x protons

  charge on 1 proton = 1.6 x 10^-16 C

Total positive charge = 1.6 * 10^-16 * 3.011 * 10^23 x = 4.18 * 10-7 x C

2) k Q^2 / r^2 = F

9 * 10^9 * Q^2 / ( 10000 y )^2 = x

Q^2 = 10000^2 x y^2 / (9 * 10^9 ) = 0.0111 x y^2

Q = 1.05 y x0.5

magnitude of each charge = 1.05 y x 0.5
