Answer : The [α] for the solution is, -118.8
Explanation :
Enantiomeric excess : It is defined as the difference between the percentage major enantiomer and the percentage minor enantiomer.
Mathematically,
Given:
% major enantiomer = 86 %
% minor enantiomer = 14 %
Putting values in above equation, we get:
Now we have to calculate the [α] for the solution.
Thus, the [α] for the solution is, -118.8
Answer: The molarity is 0.25 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in ml
moles of =
Now put all the given values in the formula of molality, we get
Therefore, the molarity is 0.25 M
This type of water pollution is known as thermal pollution. Thermal pollution is the release of heat into the environment. In the case of power plants they release heated water into waterways. Water is used in power plants to cool down machinery. As machines operate they release heat so the water is used as a coolant. Releasing heated water into an aquatic ecosystem reduces the oxygen carrying capacity of the water, so less oxygen is available for organisms to use for respiration.
