DEVELUPMENT (PAGPAPAUNLAD) Learning Task No. 2: Show the complete process of computation to obtain a correct answer. Example: The active ingredient in wines and other alcoholic beverages is ethanol. A 300mL sample of wine (solution) was found to contain 37.5mL of ethanol (solute). What is the percentage by volume concentration of ethanol in the wine sample? Formula: volume o solute percent by volume x 100 volume of solution - Solution: Given: volume of solute 37.5 mL volume of solution= 300 ml. volume of solute percent by volume = x 100 volume of solution 375 px 100 300 0.125 x 100 % by volume- ? = 12.5%, Take notel The volumes of the solute, solvent, and solution must be expressed in the same units, Problem #1: What is the percent by volume of a solution formed by mixing 25mL of isopropanol (solute) with 45mL water( solution Given: Solution:
