<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
Molar mass is defined as the sum of the atoms present in a compound each multiplied with the number of atoms present in it.
For a compound 
The molar mass will be = ![[(x\times \text{Molar mass of A})+(y\times \text{Molar mass of B})]](https://tex.z-dn.net/?f=%5B%28x%5Ctimes%20%5Ctext%7BMolar%20mass%20of%20A%7D%29%2B%28y%5Ctimes%20%5Ctext%7BMolar%20mass%20of%20B%7D%29%5D)
So, for the given compound 
,
The molar mass will be = ![[(1\times \text{Molar mass of Niyrogen})+(3\times \text{Molar mass of Hydrogen})]](https://tex.z-dn.net/?f=%5B%281%5Ctimes%20%5Ctext%7BMolar%20mass%20of%20Niyrogen%7D%29%2B%283%5Ctimes%20%5Ctext%7BMolar%20mass%20of%20Hydrogen%7D%29%5D)
Hence, the correct answer is Option C.
C) The atom must contain some centrally located positive charge. He called this core of positive charge the nucleus.
Explanation:
Rutherford concluded from his experiment that the atom contains some centrally located positive charge. He called the core the nucleus.
Rutherford developed the nuclear model of the atom.
- In a bid to explain his observation, Rutherford suggested the nuclear model.
- The model consists of small positively charged center called the nucleus.
- Nearly all the mass is concentrated in the nucleus.
- The extranuclear space is made up of electrons orbiting the nucleus.
