Answer : 17.12 g
Explanation:
= elevation in boiling point
= boiling point elevation constant
m= molality
given 
Molar mass of solute = 46.0 
Weight of the solvent = 150.0 g = 0.15 kg
Putting in the values
x = 17.12 g
<span>The effective nuclear charge of an atom = total electrons - inner electrons
For O, ENC = 8 - 2 = 6
For Li, ENC = 3 - 2 = 1
For C, ENC = 6 - 2 = 4
The electrons in O experience the greatest effective nuclear charge and that is why O is smaller than C (which is smaller than Li).</span>
This is true. Solid, Liquid, and Gas.
Hope that helps!!
