Answer: 1 mol of potassium phosphate.

Explanation:

Find the molar mass of potassium phosphate.

Equation of potassium phosphate = K3PO4

The molar mass of K = 39.10 g/mol, P = 30.97 g/mol, O = 16.00 g/mol (use periodic table for these values).

Then add them up together based off of the equation.

3(39.10 g/mol) + 30.97 g/mol + 4(16.00 g/mol) = 212.27 g/mol

Multiply the 212.26 grams by the molar mass (unit conversion method).

$212.26 g*\frac{1 mol}{212.27 g}$ = 1.00 mol

There is 1 mol of potassium phosphate.

Calculate the standard entropy of vaporization of ethanol at its boiling point, 352 K. The standard molar enthalpy of vaporizati

Korvikt [17]

Answer : The correct option is, (b) +115 J/mol.K

Explanation :

Formula used :

$\Delta S=\frac{\Delta H_{vap}}{T_b}$

where,

$\Delta S$ = change in entropy

$\Delta H_{vap}$ = change in enthalpy of vaporization = 40.5 kJ/mol

$T_b$ = boiling point temperature = 352 K

Now put all the given values in the above formula, we get:

$\Delta S=\frac{\Delta H_{vap}}{T_b}$

$\Delta S=\frac{40.5kJ/mol}{352K}$

$\Delta S=115J/mol.K$

Therefore, the standard entropy of vaporization of ethanol at its boiling point is +115 J/mol.K

Decreasing the saturation of the fatty acid chains on a particular type of phospholipid would result in the formation of _____.

LUCKY_DIMON [66]

Answer:

The correct answer is "more fluid bilayers".

Explanation:

A fatty acid is a biomolecule of lipidic nature formed by a long hydrocarbon chain of different lengths at the end of which there is a carboxyl group.

The wall of the gallbladder consists of three main layers of tissue: The mucosa covers the wall of the gallbladder. The muscular layer of smooth muscle. The serosa, which is the outer layer.

By decreasing the saturation of the fatty acid chains in phospholipids, the bile layers would reduce their thickness and become more fluid.
