Molarity is defined as the moles of solute per liter of solution. . Where M is molarity, n is the number of moles and V is the volume. First we must find the molar mass of
which is 109.98 g/mol
Then we find the molarity using above equation
(c) He, Na, Mg (increasing order of melting point).

Answer:
Option a: positron emission.
Explanation:
In the transformation we have:
⁶⁷Ga → ⁶⁷Zn
The reaction is:
For Ga to become Zn, the atom nucleus has to lose a proton, so in the given options, the reaction that involves the transformation of a proton is the option a, positron emission.
In a positron emission, a proton becomes into a neutron and a positron:
Therefore, the correct answer is option a: positron emission.
