Some Basic Concepts Of Chemistry Question 271
Question: 10 $ dm^{3} $ of $ N _2 $ gas and 10 $ dm^{3} $ of gas X at the same temperature contain the same number of molecules. The gas X is
Options:
A) $ CO $
B) $ CO _2 $
C) $ H _2 $
D) NO
Show Answer
Answer:
Correct Answer: A
Solution:
If same volume is occupied by the gas, the no. of molecules are same, so no. of moles are same. 1 mole of $ N _2 $ gas $ =2\times 14=28gm $
1 mole of $ CO $ gas $ =12+16=28gm $
