NEET Chemistry Atomic & Molecular Mass Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Empirical Formula | (i) Exact number of atoms in a molecule |
| (b) Molecular Formula | (ii) Simplest whole number ratio of atoms |
| (c) Molar Mass | (iii) Mass of carbon-12 atom |
| (d) Mass Percent | (iv) Percentage of an element in a compound |
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The empirical formula represents the simplest whole number ratio of various atoms in a compound (a-ii), while the molecular formula shows the exact number of different types of atoms (b-i). The molar mass is based on the mass of a carbon-12 atom (c-iii), and mass percent indicates the percentage of an element in a compound (d-iv).
