Best ResponseYou've already chosen the best response.02 C8H18 + 25 O2 = 16 CO2 + 18 H2O the ratio between C8H18 and CO2 is 2 : 16 moles CO2 formed = 3.5 x 16/ 2= 28

Best ResponseYou've already chosen the best response.0We shall assume that C8H18 is in excess. First calculate the moles of O2: n(O2) = 300 g / 32.00 g/mol = 9.375 mol Determine the moles H2O using the mole ratio; 18 moles of H2O are formed when 25 moles of O2 react. n(H2O) = (9.375 mol O2)(18 mol H2O / 25 mol O2) = 6.75 mol H2O Multiply the moles of H2O by Avogarod's number to determine # of molecules: (6.75 mol)(6.01x10^23 molecules/mol) = 4.1x10^24 molecules

Best ResponseYou've already chosen the best response.0Could you help me with this last problem? I already did it, but it would be great if you could check it. It's a23.png, and the equation is at the top.

Best ResponseYou've already chosen the best response.0well 2 moles of C8H18 yeilds 16 moles of CO2 1 mole of C8H18 will yeild 8 moles of CO2 therefore 3.5 moles of C8H18 will yeild 8*3.5=28 moles of CO2
