Passage / Comprehension
Three flasks A, B and C have equal volumes. A is maintained at 300 K, B at 600 K and C at 900 K. Flask A contain H2 gas, flask B contain CH4 gas and flask C contain O2 gas, and masses of all gases are same. Assume ideal behaviour of gases.
Flask containing greater number of molecules is
Options:
Answer:
A
Solution:
For equal mass m, moles n = m/M: nA = m/2, nB = m/16, nC = m/32. Since nA > nB > nC, flask A (H2) has the most molecules. Hence Ans (a).
