Type: MCQ-numerical-Medium-Class 11
Volume occupied by one molecule of water (density = 1g cm⁻³) is :
A
0 × 10⁻²³ cm³
B
5.5 × 10⁻²³ cm³
C
9.0 × 10⁻²³ cm³
D
6.023 × 10⁻²³ cm³
Correct Answer
Option A
Detailed Explanation
The volume of one molecule of water can be calculated using the density and Avogadro's number. Given the density of water is 1 g/cm³, the volume of one molecule is approximately 3.0 × 10⁻²³ cm³.
