Answer:
Mass = 3. 6 ( 2 significant digits)
Explanation:
Number of moles = 0.045
Mass = ?
Relationship between number of moles and mass is given as;
Number of moles = Mass / molar mass
Mass = Number of moles * Molar mass
Mass = 0.045 * 80.91g/mol
Mass = 3.641
Mass = 3. 6 ( 2 significant digits)
<h3>Answer:</h3>
We will neither give the Hypertonic Solution nor the Isotonic Solution but the patient will be given an Hypotonic Solution.
<h3>Explanation:</h3>
As the patient is taken for heat stroke and has resulted in dehydration so it means that the water content in the cells of the patient has been decreased and the solute content is being increased. Hence, this case is known as <em>Hypertonicity</em>. So, in order to make the concentration of water and solute balance (<em>Isotonicity</em>) on both sides (inside and outside the cells) we should administer an <em>Hypotonic solution</em> into the patient body. Therefore, the higher concentration of solutes in cells will drag the water content from hypotonic solution and gradually the process will attain an isotonic environment.
Answer: D. Circulatory System
Explanation: The circulatory system transports gases (oxygen, carbon dioxide), nutrients, and wastes found in the blood throughout the body.
Answer:
Explanation:
Considering the Henderson- Hasselbalch equation for the calculation of the pH of the buffer solution as:
Where Ka is the dissociation constant of the acid.
pKa of phenolphthalein = 9.40
pH = 10.9
So,
