Consider the fermentation reaction of glucose: c6h12o6 → 2c2h5oh + 2co2 a 1.00-mol sample of c6h12o6 was placed in a vat with 100 g of yeast. if 67.7 g of c2h5oh was obtained, what was the percent yield of c2h5oh?

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
