Answer:
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value 
Given, Wavelength = 1040 nm
Also, 1 m = 
nm
So,
Wavelength = 
m
Thus, Frequency is:
We can characterize properties of a substance to identify it because it helps us determine how the substance should be used. We can identify a substance by using physical or chemical properties. These help us by telling us which chemical we are looking at.
I hope this helps.. I wasn't sure what kind of answer you were looking for.
I am assuming that this compound contains carbon, hydrogen and oxygen. The molar mass of carbon, hydrogen and oxygen is 12, 1 and 16 grams/mol. Given these molar mass we now need to know the number of C H and O in the compound. To have 132 the compound must be C6H12O3
