Explanation / Answer

(2)

There are four atoms in a FCC unit cell.

(3)

The unit cell shown is body centred tetragonal.

(5)

Moles of acid = Mass/MW = 30/98.079 = 0.3059

Molarity = Moles/Volume = 0.3058/2 = 0.1529 M

Since acid is diprotic, so

Normality = 2*Molarity = 2*0.1529 = 0.3059 N

Hope this helps !
