50.5 g C_(5){H}_(12) Molar mass C_(5)H_(12) =5*12+12*1=72 g/mol 50.5 g* (1 mol/72 g)=0.706 mol C_(5)H_(12) C_(5)H_(12) + 8O_(2) ---\ \textgreater \ 5CO_(2) +6 H_(2)O 1 mol C_(5)H_(12) ----- 6 mol H_(2)O 0.706 mol C_(5)H_(12) --- x mol H_(2)O x= (0.706*6)/1= 4.24 mol H_(2)O Under STP water is liquid. M(H_(2)O})=2*1.0+16.0=18.0 (g)/(mol) 4.24 mol H_(2)O * (18.0 g)/(1 mol) = 76.3 g H_(2)O Density H_(2)O = 1 (g)/(ml) 76.3 g /(1 g/ml) = 76.3 ml of water Answer 76.3 ml of the water.
