The volume of 10 gram of gas X is 5.6 liter at stp what is the molecular weight of x
Correct answer: B. 40
- A. 20
- B. 40
- C. 50
- D. 60
Explanation
Volume= 5.6 liter. Mass= 10 grams. Volume/22.4 = mole 5.6 /22.4= 0.25 moles. Mole = Mass / Mr Mr = Mass / Mole = 10 / 0.25 = 40.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
