NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 11
A diagram shows a sphere representing a hydrogen atom with its radius labeled as 0.5 Å. What is the total atomic volume in cubic meters of a mole of hydrogen atoms?
A
5.235 × 10^-31 m³
B
256 × 10^-30 m³
C
189 × 10^-31 m³
D
456 × 10^-30 m³
Correct Answer
Option D
Detailed Explanation
The atomic volume of one hydrogen atom with radius 0.5 Å is calculated using the formula for the volume of a sphere (V = 4/3πr³) and converting Å to meters. The total volume for a mole is the atomic volume multiplied by Avogadro's number.
