Question

How many coulombs of positive charge are there in 4.00 kg of plutonium, given atomic mass is 244 and that each plutonium atom has 94 protons?

Answer 1

The number of moles is n = male M = 4.00 times 10^3G/244g/mole = 16.4mole the number of atoms presented is N = N Na = 16.4mole 6.023 times 10^23 atoms/mole = 9.87 times 10624 atoms the total number of protons presented is np = n 94 = 9.87 times 10^24atoms 94 = 9.28 times 10^26 therefore the total charge of plutonuium is Q = np e = 9.28 times 10626 1.6 times 10^-19c = 1.48 times 10^8c
