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 720. g sucrose undergoes fermentation and 323.0 g ethanol is obtained.

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.

What is the empirical formula of c6h18o3? ch3o c2h5o c2h6o c2h5o5
