Type: MCQ-diagram based-Hard-Class 11
Consider a diagram of a hydrogen atom with an electron orbiting the nucleus. If the size of the hydrogen atom is about 0.5 Å, what is the total atomic volume in m³ of a mole of hydrogen atoms?
A
14 × 10⁻²⁹ m³
B
6.02 × 10⁻²⁸ m³
C
18 × 10⁻³⁰ m³
D
00 × 10⁻²⁷ m³
Correct Answer
Option A
Detailed Explanation
The atomic volume of a single hydrogen atom is roughly the volume of a sphere with radius 0.5 Å. For a mole, you multiply by Avogadro's number.
