Chemistry Question on States of matter
A 10.0 L flask contains 64 g of oxygen at 27°C. (Assume O2 gas is behaving ideally). The pressure inside the flask in bar is (Given R = 0.0831 L bar K-1 mol-1)
A
2.5
B
498.6
C
49.8
D
4.9
Answer
4.9
Explanation
Solution
PV = nRT
P = (2 x 0.0831 x 298)/10
P = 4.95 bar
