Answer:

molality, mole fraction, solvent, solute, molarity.

Explanation:

<em>The expression of concentration that provides the moles of solute per kilograms of solvent is </em><em>molality</em><em>.</em>

b=\frac{n_{solute}}{m_{solvent}(kg)}

<em>If you place 5 moles of sodium chloride and 4 moles of sucrose into 11 moles of water, the </em><em>mole fraction</em><em> of sodium chloride would be 0.25 </em>

X(NaCl)=\frac{molesNaCl}{moles_{solution}} =\frac{5mol}{20mol} =0.25

<em>A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the </em><em>solvent</em><em> is water. </em>

The solvent is the component in major proportion and the one that defines the state of the solution.

<em>A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the </em><em>solute</em><em> is sodium chloride. </em>

The solute is the component in minor proportion.

<em>A way to express concentration that provides the moles of solute per liter of solution is </em><em>molarity</em><em>.</em>

M=\frac{n_{solute}}{V_{solution}(L)}

Consider the following two substances andtheir vapor pressures at 298 \rm K.Substance Vapor pressure (\rm mmHg) A 275 B 459Based
Dafna11 [192]

Explanation:

The pressure exerted by vapors or gas on the surface of a liquid is known as vapor pressure.

This means that weaker is the intermolecular forces present in a substance more easily it can form vapors. As a result, it will have high vapor pressure.

As substance B has high vapor pressure which means that it has weak intermolecular forces.

Also, stronger is the intermolecular forces present in a substance more will be its boiling point. Hence, more energy or temperature is required to break the bonds. Hence, substance A has higher boiling point and high heat of vaporization.

When surrounding pressure is less than or equal to its vapor pressure then substance B boils into the gas phase. Hence, substance B will be a gas at 300 mm Hg.

Therefore, we can conclude that characteristics of the two substances will be as follows.

(a) Substance B - has weaker intermoclcular

(b) Substance A - has a higher boiling point

(c) Substance B - is a gas at 300 mm Hg

(d) Substance A - has a higher heat of vaporization

By which mechanism would a steroid molecule diffuse into the cell?
LUCKY_DIMON [66]

Answer: Directly through the phospholipid membrane

Explanation:

The cell membrane consist of a phospholipid bilayers structure. In the interior of the membrane, the phospholipid tail are hydrophobic, which makes the cell membrane to be selectively permeable, it is permeable to non polar molecules and impermeable to polar molecules.

Because Steroids are fat soluble, non polar compounds, they can diffuse directly through the hydrophobic, non polar core of the phospholipid bilayer without the use of carrier proteins.

What is the vapor pressure in equilibrium with when the substance has reached its boiling point
S_A_V [24]

Answer:

The boiling point of a liquid is the temperature at which its vapor pressure is equal to the pressure of the gas above it.The normal boiling point of a liquid is the temperature at which its vapor pressure is equal to one atmosphere (760 torr). Microscopic view inside a bubble in boiling water.
