<h3>
Answer:</h3>
318.405 g
<h3>
Explanation:</h3>
We are given;
- Volume of K₃PO₄ solution to be prepared as 750.0 mL or 0.75 L
- Molarity of the solution to be prepared as 2.00 M
We are required to determine the mass of K₃PO₄ to be measured.
<h3>Step 1: Determine the number of moles of K₃PO₄</h3>
Molarity = Moles ÷ Volume
Rearranging the formula;
Number of moles = Molarity × Volume
Therefore;
Moles of K₃PO₄ = 2.00 M × 0.75 L
= 1.5 moles
<h3>Step 2: Determine the mass of K₃PO₄ to be measured</h3>
Mass = Number of moles × Molar mass
Molar mass of K₃PO₄ = 212.27 g/mol
Therefore;
Mass of K₃PO₄ = 1.5 moles × 212.27 g/mol
= 318.405 g
Therefore, the mass of K₃PO₄ that should be weighed is 318.405 g
The TLC analysis is aimed to verify the completion and the product of the reaction. potassium permanganate is then added to the TLC plate to detect the existence of double bond in the final product. Potassium permanganate reacts with the double bond and makes the spot yellow-brown.
Electrophilic addition is an exothermic reaction, in which a pi bond is turned into a sigma bond. The double bond in the alkene acts as a nucleophile. Halogens, halogen acids , hypohalous acids, sulphonic acid and water can be used as the electrophilic reagent. In this experiment, bromination of cholesterol is performed. The electrophilic attack of Br2generates acyclic bromonium ion. The addition gives a trans stereochemistry to the bromonium ion. As the Br-attacks the most substituted carbon in anti-periplanar fashion by SN2reaction, it would result in the inversion of configuration at that specific carbon.

Answer:
mitochondria are present in the cells of all types of aerobic organisms like plants and animals, whereas Chloroplast is present in green plants and some algae, protists like Euglena. Mitochondria is the colourless, bean shape organelles. Chloroplasts are green colour and disc shape organelles.
