Answer:
I believe you are asking about the objective lens or eyepiece.
Explanation:
Objective lenses are used to magnify objects enough for you to see them in great detail
Eyepiece/Ocular is what you look through at the top of the microscope.
A tube connects the eyepiece lens to objective lenses, which enhance the magnification power of the eyepiece lens. Both the eyepiece and the objective lens contribute to the magnification of the object.
The eyepiece lens usually magnifies 10x, and a typical objective lens magnifies 40x.

Answer:
The correct answer is 4.16 grams.
Explanation:
Based on the given information, the concentration of KCl solution is 16 % m/v, which means that 100 ml of the solution will contain 16 grams of KCl.
The molarity of the solution can be determined by using the formula,
M = weight/molecular mass × 1000/Volume
The molecular mass of KCl is 74.6 grams per mole.
M = 16/74.6 × 1000/100
M = 16/74.6
M = 2.14 M
Now the weight of KCl present in the solution of 26 ml will be,
2.14 = Wt./74.6 × 1000 /26
Wt. = 4.16 grams

It is because only this element have equal number of Protons (Bottom number) and are different in atomic masses (upper number)
