NEET Chemistry Atomic & Molecular Mass Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Hydrogen atom mass in amu (i) 1.0078 amu (b) Oxygen-16 atom mass in amu (ii) 15.995 amu (c) Avogadro's number (iii) 6.022 × 10^23 (d) Unified mass (iv) amu replaced by u
Choose the correct matching:
a-i, b-ii, c-iii, d-iv
a-i, b-iv, c-ii, d-iii
a-ii, b-i, c-iv, d-iii
a-iii, b-ii, c-i, d-iv
Correct Answer
Detailed Explanation
The mass of hydrogen is accurately given as 1.0078 amu, the mass of oxygen-16 as 15.995 amu, Avogadro's number is 6.022 × 10^23, and the unified mass has replaced amu. All pairs in option A are correct according to the NCERT context.
