NEET Physics (general) MCQ Question
Type: MCQ-numerical-Hard-Class 11
If the atomic volume of a hydrogen atom is calculated using its size as 0.5 Å, what is the approximate volume in cubic meters of a mole of hydrogen atoms?
A
0 × 10^-5 m^3
B
5.0 × 10^-5 m^3
C
0 × 10^-4 m^3
D
5 × 10^-4 m^3
Correct Answer
Option A
Detailed Explanation
The volume of a single hydrogen atom is calculated using (4/3)πr^3, where r = 0.5 Å = 0.5 × 10^-10 m. The total volume of a mole is this value multiplied by Avogadro's number. This calculation yields approximately 2.0 × 10^-5 m^3.
