Question

A proton, which is the nucleus of the hydrogen atom, can be modeled as a sphere with a diameter of 2.4 fm and a mass of 1.67 x 10⁻²⁷ kg. What is the diameter of the proton in meters?

1) 2.4 x 10⁻¹⁵ m
2) 2.4 x 10⁻¹⁶ m
3) 2.4 x 10⁻¹⁷ m
4) 2.4 x 10⁻¹⁸ m

Answer 1

The diameter of the proton in meters is 2.4 x 10^-15 m.

Step-by-step explanation:

In the given question, the diameter of the proton is given as 2.4 fm (femtometers). We need to convert this diameter to meters.

Since 1 fm is equal to 10-15 m, we can convert the diameter by multiplying 2.4 fm by 10-15 m/fm.

Therefore, the diameter of the proton in meters is 2.4 x 10-15 m.
