10 gm of a radioactive element is kept in a container. The element is -active. Then after one half-life:
(molar mass of the substance is 100 gm, Avogadro's number per mole)
(molar mass of the substance is 100 gm, Avogadro's number per mole)
View answer and explanation
Correct option: C
If all particles leave the container then the charge of the substance left is 4800 C
Option C (If all β particles leave the container then the charge of the substance left is 4800 C) is correct. Beta decay doesn't significantly change the mass, and the charge left after beta emission can be calculated.
