It will either be B or D, but I don't know about burial.
3.125 i believe is the answer
This statement is: False
Boiling is vaporization that occurs both below and at the surface of the liquid.
However, evaporation happens at the surface of the substance.
So, if you need to correct this statement, the correction would be:
Sublimation and evaporation happen at the surface of the substance.
Answer:
44.2 mmHg
Explanation:
We have to apply the colligative property of lowering vapor pressure:
P° - P' = P° . Xm
where P' refers to vapor pressure of solution
P° refers to vapor pressure of pure solvent
Xm is the mole fraction of solute
Let's determine the mole fraction (moles of solute / Total moles)
Total moles = Moles of solute + Moles of solvent
Moles of solute → 15 g . 1 mol/18g = 0.833 moles
Moles of solvent → 100 g . 1mol / 46 g = 2.174 moles
Total moles = 0.833 + 2.174 = 3.007
Xm = 0.833 / 3.007 = 0.277
We replace data in the formula: 61.2 mmHg - P' = 61.2 mmHg . 0.277
P' = - (61.2 mmHg . 0.277 - 61.2 mmHg) → 44.2 mmHg
