Answer :
By Avogadro's number, the positive charge of plutonium is 4.5 x 10⁸ C.
We need to know about Avogadro's number to solve this problem. Avogadro's number is the number that explains how many atoms are in one mol. The Avogadro's number is
Na = 6,02 × 10²³ atoms / mol
From the question above, we know that
m = 1.21 kg = 1210 g
Ar = 244
λ = 94 protons/atom
By using Avogadro's number, we can calculate how many plutonium atoms
N = Na . n
N = 6,02 × 10²³ x gr/Mr
N = 6,02 × 10²³ x 1210/244
N = 3.01 x 10²⁵ atoms
Find the protons
protons = λ . N
protons = 94 . 3.01 x 10²⁵
protons = 2.83 x 10²⁷
Each proton has a charge 1.6 x 10¯¹⁹ C. Hence, the positive charge of plutonium is
Q = 2.83 x 10²⁷ . 1.6 x 10¯¹⁹ C
Q = 4.5 x 10⁸ C
