Molality is defined as the number of moles of solute present in 1L of solution.
Molality (M) = No of moles of solute / 1 L of solution
Litre of solution = No of moles of solute / Molality
Molality = 0.220M
No of moles= 0.0170 mol
Volume in L = 0.0170/0.220
= 0.0772 L
Volume in mL = 77.27 mL
What is mole?
- A mole is a very important unit of measurement used by chemists.
- moles of something means there are 602,214,076,000,000,000,000,000,000,000,000 number of something.
- Chemists need to measure very small things such as atoms, molecules and other particles in moles.
- 602,214,076,000,000,000,000,000 is called Avogadro's number, abbreviated as 6.02 x
Therefore, Volume in ml of 0.220 m hbr solution is required to produce 0.0170 moles is 77.27 mL.

We are asked to provide an equation for the transformation of 2-phenylethanoic acid to 2-phenylethanol. This type of a reaction is converting a carboxylic acid to an alcohol, which is classified as a reduction reaction since we are decreasing the number of bonds to oxygen in the molecule. In order to reduce a carbonyl to an alcohol, we need a source of hydride, H⁻. Reducing the carboxylic acid once will convert it to the aldehyde. However, we need to reduce the functional group all the way down to an alcohol, which is another reduction step after aldehyde formation. Therefore, the hydride source of choice is lithium aluminum hydride, LiAlH₄.
A reaction scheme is provided to show the reaction of the reduction of carboxylic acid to alcohol. The first step is addition of lithium aluminum hydride which does the reduction, and the second step is a work-up of acid which protonates the alcohol to get the final product.

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.
