Answer : The vapor pressure of solution is 23.67 mmHg.
Solution:
As the relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
The formula for relative lowering of vapor pressure will be,
where,
= vapor pressure of pure solvent (water) = 23.76 mmHg
= vapor pressure of solution= ?
= mass of solute (sucrose) = 12.25 g
= mass of solvent (water) = 176.3 g
= molar mass of solvent (water) = 18.02 g/mole
= molar mass of solute (sucrose) = 342.3 g/mole
Now put all the given values in this formula ,we get the vapor pressure of the solution.
Therefore, the vapor pressure of solution is 23.67 mmHg.
B. Scientific claims can be verified through observation and experimentation, while pseudoscientific claims cannot. At least I think it is right.
First option.
The male tails are more attractive because of their long feathers , meanwhile the female tails are shorter than expected!
<span>The form of energy related to measurement of kinetic energy is heat energy. Basically, thermal energy is related to the measurement of molecula kinetics of a substance. It is due to the thermoagitation of the partices of the substances, which keep on moving. </span>
The correct answer of the given question above would be FLAGELLA. The structure that makes it possible for some kinds of prokaryotic cells to move around is the FLAGELLA. Prokaryotic cell is one of the types of cells. The other type is the Eukaryotic cell. This cell is found in two Kingdoms of life which are Archaea and Bacteria. Hope this answer helps.
