Answer: hopefully this is right UwU
Explanation: The infrared spectrum of a sample is recorded by passing a beam of infrared light through the sample. When the frequency of the IR is the same as the vibrational frequency of a bond or collection of bonds, absorption occurs. Examination of the transmitted light reveals how much energy was absorbed at each frequency (or wavelength).

Answer:200/3 M which is approximately equal to 66.6667 M
Explanation:Molarity is defined as the number of moles of solute per liter of solution.
It can be calculated as follows:

We are given that:
number of moles of solute = 8 moles
volume of solution = 120 ml = 0.12 liters
Substitute with the givens in the above equation to get the molarity as follows:
molarity =
