The molar mass of KCl is 74. 55 g/mol. If 8. 45 g KCl are dissolved in 0. 750 L of solution, what is the molarity of the solutio
rosijanka [135]

Molarity is the strength of the solution or the ratio of the moles and the volume of the solution. The molarity of the solution is 0.1516 mol per Liter.

<h3>What is molarity?</h3>

Molarity is the molar concentration of the solution that tells about the amount of the solute or the substance dissolved in the given amount of the solution.

Given,

  • Mass of potassium chloride = 8.45 g
  • Molar mass of potassium chloride = 74. 55 g/mol
  • Volume of the solution = 0.750 L

Moles can be calculated by:

\begin{aligned}\rm Moles &= \rm \dfrac{Mass }{\rm Molar \;mass}\\\\&= \dfrac{8.45}{74.55}\\\\&= 0.1133\;\rm  mol\end{aligned}

Calculate molarity by:

\rm Molarity = \dfrac{moles}{\text{Volume in L}}

Substituting values in the equation:

\begin{aligned}\rm  Molarity &= \dfrac{0.1133}{0.750}\\\\&= 0.1516 \;\rm mol\;L^{-1}\end{aligned}

Therefore, the molarity of the solution is 0.1516 mol per Liter.

Which enzyme is not part of gluconeogenesis?
lisov135 [29]

Phosphoenol pyruvate enzyme is not part of gluconeogenesis.

<h3>Phosphoenol pyruvate</h3>

The ester formed when pyruvate and phosphate are combined to form an enol results in phosphoenol pyruvate (2-phosphoenolpyruvate, or PEP). As an anion, it exists. In biochemistry, PEP is a crucial intermediary. Involved in glycolysis and gluconeogenesis, it boasts the highest-energy phosphate bond yet discovered in an organism (61.9 kJ/mol). It also plays a role in carbon fixation and the manufacture of a number of aromatic chemicals in plants. In bacteria, it provides energy for the phosphotransferase system. Enolase reacts with 2-phosphoglyceric acid to produce PEP as a result. Pyruvate kinase (PK) converts PEP to pyruvic acid, and this process produces adenosine triphosphate (ATP) via substrate-level phosphorylation. One of the main units of currency for chemical energy in cells is ATP.
