Wavelengths are often represented in nm. What is the diameter of a helium (He) atom in
nm if it is equivalent to 1.0x10^-13 km?​

Respuesta :

Answer:

Diameter He = 0,1 nm.

Explanation:

Km to nm:

⇒ Diameter He = 1.0 E-13 Km * ( 1000 m / Km ) * (  1 E9 nm / m )

⇒ Diameter He = 0.1 nm

Answer: The diameter of helium atom is 0.1 nm.

Explanation:

We are given:

Diameter of helium atom = [tex]1.0\times 10^{-13}km[/tex]

To convert this diameter from kilometers to nano meters, we use the conversion factor:

[tex]1km=10^{12}nm[/tex]

Converting the above diameter into nano meters, we get:

[tex]\Rightarrow (1.0\times 10^{-13}km)\times (\frac{10^{12}nm}{1km})\\\\\Rightarrow 0.1nm[/tex]

Hence, the diameter of helium atom is 0.1 nm
