Answer : The mole fraction of the non-volatile solute in the solution is 0.195
Explanation :
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.
Formula used :


where,
= vapor pressure of the pure solvent (acetone) = 266 torr
= vapor pressure of the solution = 214 torr
= mole fraction of solute = ?
Now put all the given values in the above formula, we get:



Therefore, the mole fraction of the non-volatile solute in the solution is 0.195

The formula is literally NO
Explanation:
one nitrogen atom N and one oxygen atom O.
The element sulfur is classified as a nonmetal.
Answer:
Metalloid
Explanation:
A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is neither a standard definition of a metalloid nor complete agreement on the elements appropriately classified as such
