Respuesta :
Total positive charge in 1.80 kg of plutonium is 13365,04 x 10^4 C
Solution:
1 mole of plutonium = 244 gm
3.6 kg of plutonium = 3.6 x 1000 = 3600 gm
Number of moles = 3600/244 = 14.754 moles
One moles of plutonium contains protons 6.023 x 10^23 x 94
Total number of protons in 14.754 moles = 6.023 x 10^23 x 94 x 14.754
= 8353.15 x 10^23
Total Positive charge = 8353.15 x 10^23 x 1.6 x 10^-19
Total positive charge = 13365,04 x 10^4 C
