MCQ practice · SSC Chemistry Board questions · Chapter 6: Concept of Mole and Chemical Counting
The conditions of molarity are:
- i. a fixed temperature
- ii. a fixed pressure
- iii. 1 liter of solution
Think it through first, then pick an option.
- a i and ii
- b i and iii
- c ii and iii
- d i, ii and iii
Answer and explanation
Correct answer: b i and iii
The definition names a fixed temperature and 1 liter of solution; there is no condition on pressure.
Why the other options are wrong
- a i and ii: ii is false: the definition of molarity sets no condition on pressure.
- c ii and iii: ii is false: pressure is not a condition of molarity; and i is left out.
- d i, ii and iii: ii is false: there are two conditions, a fixed temperature and 1 liter of solution.
