NEET Chemistry Mole Concept Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) 1 mol of hydrogen atoms | (i) 6.022 × 10²³ water molecules |
| (b) 1 mol of water molecules | (ii) 6.022 × 10²³ formula units of sodium chloride |
| (c) 1 mol of sodium chloride | (iii) 6.022 × 10²³ atoms |
| (d) 1 mol of carbon dioxide | (iv) 6.022 × 10²³ molecules |
a-iii, b-i, c-ii, d-iv
a-iii, b-ii, c-i, d-iv
a-i, b-iii, c-ii, d-iv
a-ii, b-iv, c-iii, d-i
Correct Answer
Detailed Explanation
1 mol of hydrogen atoms corresponds to 6.022 × 10²³ atoms, 1 mol of water molecules corresponds to 6.022 × 10²³ water molecules, and 1 mol of sodium chloride corresponds to 6.022 × 10²³ formula units. This is consistent with the definition of the mole and Avogadro's number.
