<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.
According to Arrhenius definition of acids, 
is an acid.
According to Arrhenius definition of acids and bases, acid is any substance that produces hydrogen ion in solution as its only positive ion.
Following this definition, let us now consider what happens when is introduced into a water;
(aq)-------> NH3(aq) + 
(aq)
Hence, according to Arrhenius definition of acids, is an acid.
For another example of Arrhenius acids, see

<span>I think the correct
answer is 109.5 degrees. The bond angle of a chlorite ion or ClO2- ion is 109.5
and has a bent shape. This is because of two groups of bonding electrons and
two lone pairs of electrons. Another example of a molecule that has a bent
molecular geometry is water. It results from its tetrahedral electron pair
shape.</span>
Density = mass / volume
D = 1 x 10⁴ / 2
D = 5000 kg/m³ in g/cm³:
1 kg/m³ ---------------- 0.001 g/cm³
5000 kg/m³ ----------- ??
5000 x 0.001 / 1 => 5.0 g/cm³
hope this helps!
The answer is B) pure water because pure water is a poor conductor of electricity.. thus a poor electrolyte
