Question

I need help please. Anything helps

Answer 1

Conversion to Millimeters (mm):

1 picometer (pm) = 1 × 10^-12 meters

1 meter = 1000 millimeters (mm)
So, the conversion formula would be:

Length in millimeters = (Length in picometers) × (1 × 10^-12) × 1000
Given that the length of a Hydrogen atom is 120 pm:

Length in millimeters = 120 × (1 × 10^-12) × 1000 = 0.12 mm

Conversion to Kilometers (Km):

1 picometer (pm) = 1 × 10^-12 meters

1 meter = 0.001 kilometers (Km)
So, the conversion formula would be:

Length in kilometers = (Length in picometers) × (1 × 10^-12) × 0.001
Given that the length of a Hydrogen atom is 120 pm:

Length in kilometers = 120 × (1 × 10^-12) × 0.001 = 1.2 × 10^-13 Km

Hope this helps, I’m like 96% sure I didn’t mess up anything.

Answer 2

Answer:The length of a hydrogen atom is 120 picometers (pm) . To convert this length into millimeters, we can use the following conversion factor:

1 millimeter (mm) = 10^12 picometers (pm)

Therefore, the length of a hydrogen atom in millimeters is:

120 pm × (1 mm / 10^12 pm) = 0.00000000012 mm

To convert this length into kilometers, we can use the following conversion factor:

1 kilometer (km) = 10^12 picometers (pm)

Therefore, the length of a hydrogen atom in kilometers is:

120 pm × (1 km / 10^12 pm) = 0.00000000012 km

In summary, the length of a hydrogen atom is 0.00000000012 millimeters or 0.00000000012 kilometers.
