JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
Number of moles and number of molecules in \(1.4187\) L of \(SO_2\) at STP respectively are:
- A \(0.1266; 3.812 \times 10^{22}\)
- B \(0.0633; 3.812 \times 10^{22}\)
- C \(0.1266; 7.6238 \times 10^{22}\)
- D \(0.0633; 7.6238 \times 10^{22}\)
Answer & Solution
Correct Answer
(B) \(0.0633; 3.812 \times 10^{22}\)
Step-by-step Solution
Detailed explanation
Volume of \(SO_2\) at STP \(= 1.4187\) L Molar volume of an ideal gas at STP is approximately \(22.414\) L. Number of moles \(n = \dfrac{\text{Volume}}{\text{Molar Volume}} = \dfrac{1.4187}{22.414} = 0.0633\) Number of molecules \(= n \times N_A\) Number of molecules…
