Answer:Mass of Potassium chloride =1.762g
Explanation:
Mass of empty beaker = 23.100 g
Mass of beaker with Potassium chloride = 24.862g
Mass of Potassium chloride = Final weight - initial weight = Mass of beaker with Potassium chloride - Mass of empty beaker = 24.862-23.100 = 1.762g

According to the given question, the decay series chart along with reaction equation are as follows.
(a) Lead-214 changes to bismuth-214.

(b) Bismuth-214 changes to polonium-214.

(c) Polonium-214 changes to lead-210.

Therefore, we can conclude that proper order of nuclear particle emission is beta, beta, alpha.
