1 atm of pressure is equal to all of the following except:
Correct answer: B. 769 mm Hg
- A. 76 cm Hg
- B. 769 mm Hg
- C. 760 torr
- D. 101325 Pa
Explanation
Option B is correct.The answer is 769 mm Hg. 1 atm is equal to 760 mm Hg, so 769 mm Hg is slightly greater than 1 atm. All of the other options are equal to 1 atm.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
