A molecule of water has two bond, so 1 mole of water will contain _ moles of bonds.
Correct answer: B. 2
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
Correct option is B. A molecule of water has two bonds so 1 mole of water will contain 2 mole of bonds. Each molecule of water H2O contains one oxygen bonded to 2 hydrogen atoms which is 2 bonds. There are 6.022 x 1023 molecules in one mole of water. Therefore one mole of water contains 2 x 6.022 x 1023 bonds = 1.2044 x 1024 bonds. As this is a numerical thus it can only have one answer.

About Moles and Avogadro's Number
The mole connects the microscopic number of particles with measurable mass, using Avogadro's number, 6.022 × 10²³ particles per mole. Questions involve molar mass, conversion between mass, moles and particles, percentage composition, empirical and molecular formulas, and distinguishing atoms, molecules, ions and formula units.
