Answer:
Option D
Explanation:
Molarity (M) of any solution is equal to the number of moles (n)of solute in it divided by total volume of solution (V)
Mathematically, it can be represented as
Substituting the given values, we get-
Hence, option D is correct

Answer:
Explanation:
This question involves the conversion of mass into energy: E = mc².
e + p ⟶ γ + γ
Each particle has the same mass so, in terms of mass, we can write
2e ⟶ 2γ or
e ⟶ γ
Thus, we can just convert the mass of an electron to its energy equivalent.
(a) Energy in joules
(b) Energy in kilojoules per mole
(c) Energy in electron volts
