Question:
\(1\) g of \(\text{H}_2\) contains the same number of molecules as in
\(1\) g of \(\text{H}_2\) contains the same number of molecules as in
Show Hint
Equal moles mean equal numbers of molecules.
Updated On: Oct 1, 2026
- \(14\) g of \(\text{N}_2\)
- \(18\) g of \(\text{H}_2\text{O}\)
- \(16\) g of \(\text{CO}\)
- \(28\) g of \(\text{N}_2\)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Moles of H\(_2\)
\(\frac{1}{2}=0.5\) mol.
Step 2: Check each option
(A) \(14\) g N\(_2\) is \(\frac{14}{28}=0.5\) mol. Matches.
(B) \(18\) g H\(_2\)O is \(1\) mol.
(C) \(16\) g CO is \(\frac{16}{28}=0.57\) mol.
(D) \(28\) g N\(_2\) is \(1\) mol.
Step 3: Result
Only (A) has \(0.5\) mol.
Final Answer:
\(14\) g of N\(_2\) has the same number of molecules, option (A). \[ \boxed{\text{(A)}} \]
\(\frac{1}{2}=0.5\) mol.
Step 2: Check each option
(A) \(14\) g N\(_2\) is \(\frac{14}{28}=0.5\) mol. Matches.
