In an experiment, 12.0dm3 of oxygen, measured under room conditions, is used to burn completely 0.10mol of propan-1-ol.
what is the final volume of gas, measured under room conditions?
a 7.20dm3 b 8.40dm3 c 16.8dm3 d 18.00dm3

C3H8O + 5O2 = 3CO2 + 4H2O

From Charle's law which states that volume is directly proportional with temperature at constant pressure.

V1/T1 = V2/T2

The  final volume of gas, measured under room conditions is 8.40dm3. the answer is letter B

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
