Answer:

Diameter He = 0,1 nm.

Step-by-step 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.

Step-by-step explanation:

We are given:

Diameter of helium atom =
1.0* 10^(-13)km

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


1km=10^(12)nm

Converting the above diameter into nano meters, we get:


\Rightarrow (1.0* 10^(-13)km)* ((10^(12)nm)/(1km))\\\\\Rightarrow 0.1nm

Hence, the diameter of helium atom is 0.1 nm
