Suppose you start with 1.000 g of an unknown copper compound and isolate 0.9794 g of metallic copper. What is be the formula weight of the compound if there is only one copper atom per unit formula

Ethanol (c2h5oh) is produced from the fermentation of sucrose in the presence of enzymes. c12h22o11(aq) + h2o(g) 4 c2h5oh(l) + 4 co2(g) determine the theoretical yield and the percent yields of ethanol if 680. g sucrose undergoes fermentation and 326.5 g ethanol is obtained. theoretical _ g _ percent %
