Match the intermolecular force with the physical property that will result

Chemistry

Answer:

Intermolecular forces are the forces that bind two molecules together. Physical properties are affected by the strength of intermolecular forces. Melting, boiling, and freezing points increase as intermolecular forces increase. Vapor pressure decreases as intermolecular forces increase. Hope this is what your looking for!

D is the answer, I believe.

An isolated system is one that allows neither heat or matter to enter or exit, and since the liquid remained the same temperature, one can conclude that neither energy nor matter is passing through.

The freezing point (tf) for t-butanol is 25.50°c and kf is 9.1°c/m. Usually t-butanol absorbs water on exposure to the air. If t
padilas [110]

The mathematical expression is given as:

\Delta T = k_{f}m             (1)

where, \Delta T = depression in freezing point

k_{f} = molal freezing point.

Now, first calculate the \Delta T = 25.50^{o}C -24.59^{o}C

\Delta T= 0.91^{o}C

Substitute the values in equation (1), we get

0.91^{o}C = 9.1^{o}C/m \times  m  

m = \frac{0.91^{o}C}{9.1^{o}C/m}

= 0.1 molal or  \frac{0.1 moles of water}{kg of butanol}

Now,

In 0.1 moles of water = 1 kg of butanol

So, 11.9 g of butanol = 11.9 g butanol\times \frac{0.1 mol of water}{kg butanol}

Convert gram into kilogram, (1 kg =1000 g)

= 11.9 g butanol\times \frac{0.1 mol of water}{kg butanol}\times \frac{1 kg}{1000 g}

= 0.00119 mole

Mass of water present in sample = 0.00119 mole\times 18 g/mol

= 0.02142 g

Hence, grams of water present in the sample  = 0.02142 g
