<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.

Sorry if it's wrong!!!!!!!
Answer:
There are 0.09996826 moles per liter of the solution.
Explanation:
Molar mass of HNO3: 63.02
Convert grams to moles
0.63 grams/ 63.02= 0.009996826
Convert mL to L and place under moles (mol/L)
100mL=0.1 L
0.009996826/0.1= 0.09996826 mol/L
