Final answer:
The total coulombs of positive charge in 1.19 kg of Plutonium is calculated to be 4.42 x 10^7 C.
Explanation:
The student is inquiring about the total coulombs of positive charge in a given mass of Plutonium. Before we begin, note that the charge on a single proton (same as the positive charge on a single ion) is known to be +1.602 x 10^-19 C. Each plutonium atom consists of 94 protons. Thus, the charge on one plutonium atom would be 94 times the charge on proton, i.e. 1.5048 x 10^-17 C.
Now, the number of atoms in 1.19 kg of Plutonium can be calculated using Avogadro's Number (6.02 x 10^23) and the given atomic mass of Plutonium (244), computed as: 1.19 kg * Avogadro's Number / atomic mass. Calculating gives us approximately 2.933 x 10^24 atoms. So, the total charge is just the charge on one plutonium atom multiplied by the total number of atoms, which equals 4.42 x 10^7 C.
