The volume percent of ethanol in the solution is calculated by dividing the volume of ethanol by the total volume of the solution and then multiplying by 100. The total volume of the solution is 50.0 mL (ethanol) + 300.0 mL (water) = 350.0 mL. Thus, the volume percent of ethanol = (50.0 mL / 350.0 mL) * 100 = 14.3%.
