Answer 1

16. @ they all occupy same volume 11. V = MRT - I mot X 0.0821 Lantry 298 K . 1.5 atm 16.3 18. Cha + 202 Co2 + H₂O mole of Oz = PV = 1.32 atm x 1.3L 0.0821 Lamm x 372 K 0.0562 mol mok of CO2 = 1 x mole of O2 E X0.0562 = 0.028 mol Kmal * 19. 1 mol = 22.4L 6L=6L = 0.2678 mor 22.4 L/mol Mass of CO2 i 0.2678 ml x 44 g/mol 2 11.78 = 11.89 0
