The answer you selected in the picture is correct!
Answer:
200x
Explanation:
<em>The total magnification of a microscope depends on the power of the eyepiece and that of the objective lens. It is obtained by multiplying the two factors together. </em>
The total magnification of a microscope can be mathematically expressed as:
Total Magnification = <em>ocular/eyepiece magnification x objective magnification</em>
In the illustration, eyepiece magnification = 10 and objective magnification = 20. Hence,
Total Magnification = 10 x 20 = 200x
The chemical formula would be CaCO3
