JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
Number of atoms in the following samples of substances is largest in
- A \(4.0\, g\) of hydrogen
- B \(71.0\, g\) of chlorine
- C \(127.0\, g\) of iodine
- D \(48.0\, g\) of magnesium
Answer & Solution
Correct Answer
(A) \(4.0\, g\) of hydrogen
Step-by-step Solution
Detailed explanation
\(4\,g\) of hydrogen \(= 4\) mole of hydrogen \(= 4 \times 6.023 \times 10^{23}\) atoms \(71.0\,gm\) of chlorine \( = \frac{{71.0}}{{71.0}} = 1\) moles of chlorine \(= 6.023 \times 10^{23}\) atoms \(127\,gm\) of iodine \( = \frac{1}{2}\) mole of \(I_2\)…
