Question

Gas Stoichiometry Practice What volume of O2 at 760. torr and 25 °C is needed to react fully with 3.2 g of C H(propane)? 2 C,H. (g) + 7 02(g) → → 4CO2 (g) + 6 H20 (1)

Answer 1

pressure of Oz 7) 760 tom [latm=760 fom] = 1 atm T=256=273.15+25 [0c2273.15] = 298.15% mass of C2H6 = 3.2g made of calea given mass malar mass malar mass of GHAZ 2X12+6X1 X 3 ~ 308/meel male of GHG = 3:2 20.107 meel Ceanned with camscanner male of Cz He s orloq meel CScanned with CamScanner

262 H6 (g) +702(g) it y con + 6H2O (1) Cq H6 (g) + Z2 021g, 2 CO2(g) + 3428 (1). we know that I male of Cat6 reacts with Z male of Oz gas. . imale of Ca HG - Z male of a - 0.107 male of 1276= Zx 0.107 male of oz male of O₂ = 0.3745 mal .

We know that ideal gas equation ..puanRT 1x Vo2 = (0.3745) R (298.15) - 2=0.08205 Latma malek Vox = (113.650R Noz? (11.65) (0-08205) No, a 9016 Litre Scanned with CamScanner
