Answer:
The transmittance is the amount of energy that a body goes through in a certain amount of time without being absorbed and the absorbance is the amount of light that is absorbed by a solution.
There is no difference between absorptivity and molar absorptivity because the two terms express the same idea, because molar absorptivity is the absorbance of a solution per unit path length and concentration, so that the absorbance is proportional to concentration.
Answer:
<h3>The answer is 2.65 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 2 g
density = 0.756 g/mL
So we have
We have the final answer as
<h3>2.65 mL</h3>
Hope this helps you

Explanation:
Alcohols have higher boiling points than do ethers and alkanes of similar molar masses.
<h3>What is meant by Boiling Point ?</h3>
The temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid is called the boiling point of the substance.
Approximately boiling point of Ethanol: 78.4°C, ether: 34.6°C, ethanes: 68°C
The reason for the difference is that it takes more energy to separate alcohol molecules then it does to separate alkane molecules and ether molecules.
The OH group in alcohol allows molecules to engage in hydrogen bonding.
Therefore Boiling point are in the order ;
Alcohol > alkane > ethers
