It's very simple.
Energy =
![\frac{hc}{\lambda}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bhc%7D%7B%5Clambda%7D%20)
where, h= Planck's constant = 6.6 x
![m^2 kg/s](https://tex.z-dn.net/?f=m%5E2%20kg%2Fs)
c= speed of light = 3 x
![10^{8}](https://tex.z-dn.net/?f=%2010%5E%7B8%7D%20)
m/s
![\lambda](https://tex.z-dn.net/?f=%20%5Clambda%20)
= wavelength
So, energy =
![\frac{6.6 \times 10^{-34} \times 3 \times 10^{8}}{120}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6.6%20%5Ctimes%2010%5E%7B-34%7D%20%5Ctimes%203%20%5Ctimes%2010%5E%7B8%7D%7D%7B120%7D%20)
= 1.65 x
![10^{-27}](https://tex.z-dn.net/?f=%2010%5E%7B-27%7D%20)
J
=1.65 x
![10^{-30}](https://tex.z-dn.net/?f=%2010%5E%7B-30%7D%20)

The minor components in a mixture are called: C. impurities.
A mixture refers to a combination of two (2) or more substances present in varied proportion and can be visibly seen with the human naked eyes.
Basically, there are two main types of mixture and these include;
In Chemistry, the minor components in a mixture are called impurities.
Impurities can be defined as minute or little (tiny) chemical substances that are present in a mixture and as such making it impure. Thus, impurities are the minor components present in small quantities in a mixture.

Answer:
![m=1x10^{-6}g](https://tex.z-dn.net/?f=m%3D1x10%5E%7B-6%7Dg)
Explanation:
Hello,
In this case, since one drop equals 0.05 mL of the given solution, for a concentration 0.02 g/mL, the grams of oleic acid in one drop turns turn out:
![m=0.02\frac{g}{L}*0.05mL*\frac{1L}{1000mL}\\ \\m=1x10^{-6}g](https://tex.z-dn.net/?f=m%3D0.02%5Cfrac%7Bg%7D%7BL%7D%2A0.05mL%2A%5Cfrac%7B1L%7D%7B1000mL%7D%5C%5C%20%20%5C%5Cm%3D1x10%5E%7B-6%7Dg)
Best regards.
