2 liter
Because the volume is 2 liter and the pressure and temperature are constant so nothing is happening.
Answer:
2
Explanation:
4s2 has 2 valence electrons
Weight/volume percentage = mass of the solute/volume of solution x 100
mass of the solute= 12grams
volume of solution = 400ml
therefore % (w/v) = 12 / 400 x100 = 3%

Phenobarbital is derivative of
Barbituric Acid and Barbituric Acid is derivative of
Urea. (structures shown in Fig below)
Urea has H</span>₂N- group attached to Carbonyl Group (C=O), and such class of comounds conataining H₂N-C=O bond are called as Amides.
Result: So, <span>Phenobarbital belongs to
Amides.</span>
