An organelle was magnified 800 times by an electron microscope.its diameter was 2 millimeters.calculate the actual diameter micrometers.??

To calculate the actual diameter in micrometers, we need to divide the magnified diameter by the magnification factor.

Actual diameter = Magnified diameter / Magnification factor
Actual diameter = 2 mm / 800
Actual diameter = 0.0025 mm

Therefore, the actual diameter of the organelle is 0.0025 millimeters or 2.5 micrometers.

1. Convert millimeters to micrometers:

1 millimeter (mm) = 1000 micrometers (µm)
2 mm = 2 x 1000 µm = 2000 µm

2. Calculate the actual diameter:

Actual diameter = Original diameter / Magnification
Actual diameter = 2000 µm / 800
Actual diameter = 2.5 µm

Therefore, the actual diameter of the organelle is 2.5 micrometers.
