Answer: Option (d) is the correct answer.
Explanation:
A tetarhedral geometry is the geometry which includes four atoms bonded to the central atom and it does not contain any lone pair of electron.
For example, has tetrahedral geometry.
Thus, we can conclude that a molecule which contains four bonded pairs of electrons and zero lone pairs. The name of the molecular geometry is tetrahedral.
Answer : The the concentration of in mass percent is, 41.18 %
Solution : Given,
Molar mass of water = 18 g/mole
Molar mass of = 110.98 g/mole
First we have to calculate the mole fraction of solute.
According to the relative lowering of vapor pressure, the vapor pressure of a component at a given temperature is equal to the mole fraction of that component of the solution multiplied by the vapor pressure of that component in the pure state.
where,
= vapor pressure of the pure component (water) = 92.6 mmHg
= vapor pressure of the solution = 83.1 mmHg
= mole fraction of solute,
Now put all the given values in this formula, we get the mole fraction of solute.
Now we have to calculate the mole fraction of solvent (water).
As we know that,
The number of moles of solute and solvent will be, 0.102 and 0.898 moles respectively.
Now we have to calculate the mass of solute, and solvent,
.
Mass of solution = Mass of solute + Mass of solvent
Mass of solution = 11.32 + 16.164 = 27.484 g
Now we have to calculate the mass percent of
Therefore, the the concentration of in mass percent is, 41.18 %
