Nady [450]

Answer:

0.825 M

Explanation:

The osmotic pressure is a colligative property, that can be calculated using the following expression.

π = M × R × T

where,

π is the osmotic pressure

M is the molarity

R is the ideal gas constant

T is the absolute temperature (24°C + 273 = 297 K)

M = π / R × T = 20.1 atm / (0.08206 atm.L/mol.K) × 297 K = 0.825 M

g \Which substance has the lowest vapor pressure at 25 °C? Group of answer choices CH3CH2OH CH3CH2CH2OH CH3CH2CH2CH2OH CH3CH2CH2
alexdok [17]

Answer:

CH3CH2CH2CH2CH2OH.

Explanation:

Hello.

In this case, since the vapor pressure is known to be the pressure exerted by the gaseous molecules in equilibrium with a liquid, we can infer that the higher the molecule, the lower the vapor pressure because the molecules tend to be help together more strongly and more energy is required to separate them and take them from liquid to gas.

In such a way, since CH3CH2CH2CH2CH2OH is the longest molecule (five carbon atoms) it would be more stable at liquid phase which means that it has less molecules moving to gaseous phase, which is also related with the lowest vapor pressure. Conversely, CH3CH2OH has the highest vapor pressure.

Best regards.

What precautions must be taken when you introduce a mixture of compounds to be separated onto a liquid chromatography column?
earnstyle [38]

<span>The slim exit of the column is first persisted with glass wool or a permeable plate in order to sustain the column packing element and keep it from getting out of the tube. Then the adsorbent solid, which is usually a silica, is firmly packed into the glass tube to make the separating column. The packing of the non-moving phase into the glass column must be done with precaution to create an even distribution of material. An even distribution of adsorbent material is very important to lessen the existence of air bubbles and/or channels inside the column. To finish preparing the column, the solvent to be used as the mobile phase is delivered through the dry column. Then the column is said to be "wetted" and the column must stay wet throughout the entire procedure. Once the column is properly prepared, the sample to be separated is placed at the top of the wet column.</span>
