Final answer:
The ocular lens magnification for a microscope with a total magnification of 1,500x using a typical 100x oil immersion objective is most likely 10x, as this is the closest standard magnification value.
Step-by-step explanation:
To calculate the ocular lens magnification of a microscope when the total magnification and objective lens magnification are known, you can use the formula:
Total magnification = Objective lens magnification × Ocular lens magnification
In this case, the microscope has a total magnification of 1,500x. If the microscope is using the oil immersion objective, which typically has a magnification power of 100x, we can rearrange the formula to solve for the ocular lens magnification as follows:
Ocular lens magnification = Total magnification / Objective lens magnification
Ocular lens magnification = 1,500x / 100x
Ocular lens magnification = 15x
However, since the typical ocular lens magnifications are 5x, 10x, and 20x, and given that 15x is not standard, the correct answer would be the closest standard option which is 10x. Therefore, for a total magnification of 1,500x using a standard 100x oil immersion objective, the ocular lens would most likely have a magnification of 10x.
