. a) A pharmacist dilutes 15 ml of a 10% (m/v) saline solution (sodium chloride solution) to a final volume of 45 ml. What is the % (m/v) concentration of the
final solution?

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 %
