i got 92.3 L SO2 is this correct?
its okay its np =)
for (b) this is my work1250 g of H2O * 1 mol / 18 g = 69.44 mol of H2O # of moles of C2H5OH = 69.44 mol of H2O * 1 mol of C2H5OH / 3 mol of H2O = 23.15 mol of C2H5OH * 46 g / 1 mol = 1065 g of C2H5OH 1065 g of C2H5OH * 1 cm3 / 0.789 g = 1350 cm3 of C2H5OH
I also don't completely understand this line: 1.25 L H2O has a mass of 1.00 gram. I thought since the density was 1g /cm^3 it would be more like 1g / mL = 1000g/ L so 1250 g of H2O?
for the balanced equation i got 1C2H5OH + 3O2 ==> 2CO2 + 3H2O - why is this wrong?
