The vapor pressure of water is 23.76 mm Hg at 25 °C. A nonvolatile, nonelectrolyte that dissolves in water is sucrose. Calculate
MrRissso [65]

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,

\frac{p^o-p_s}{p^o}=\frac{w_2M_1}{w_1M_2}

where,

p^o = vapor pressure of pure solvent  (water) = 23.76 mmHg

p_s = vapor pressure of solution= ?

w_2 = mass of solute  (sucrose) = 12.25 g

w_1 = mass of solvent  (water) = 176.3 g

M_1 = molar mass of solvent (water) = 18.02 g/mole

M_2 = 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.

\frac{23.76-p_s}{23.76}=\frac{12.25\times 18.02}{176.3\times 342.3}

p_s=23.67mmHg

Therefore, the vapor pressure of solution is 23.67 mmHg.

Describe a gentle force?
Tatiana [17]

Answer:

The word gentle traces back to the Latin word gentlis, meaning “of the same clan,” and at first the world was used to describe people belonging to distinguished families, who were seen as courteous and noble. Nowadays you’re more likely to hear the word used to refer to things that are calm, moderate, and without harshness. The word is often applied to people, but it can be used more broadly to describe anything that is mild, such as "a gentle detergent" or "a gentle reminder."
