Question
**Match the gas samples at STP with their volumes/masses:** <br><br>**Column I:** <br>(A) $4.4$ g $CO_2$ <br>(B) $2$ g $H_2$ <br>(C) $16$ g $O_2$ <br>(D) $28$ g $N_2$ <br><br>**Column II:** <br>(P) $2.24$ L <br>(Q) $22.4$ L <br>(R) $11.2$ L <br>(S) $1$ mole
Answer: (A) $\RIGHTARROW$ P <BR>(B) $\RIGHTARROW$ Q, S <BR>(C) $\RIGHTARROW$ R <BR>(D) $\RIGHTARROW$ Q, S
💡 Solution & Explanation
**(A)** $4.4/44 = 0.1$ mol. Volume $= 0.1 \times 22.4 = 2.24$ L (P). <br>**(B)** $2/2 = 1$ mol (S). Volume $= 22.4$ L (Q). <br>**(C)** $16/32 = 0.5$ mol. Volume $= 0.5 \times 22.4 = 11.2$ L (R). <br>**(D)** $28/28 = 1$ mol (S). Volume $= 22.4$ L (Q).
