 Question 231944: How many liters of a 70% alchole slolution must be added to 50% liters of a 40% alcohole solution to produce a 50% alcohol solution?Answer by Alan3354(30993)   (Show Source): You can put this solution on YOUR website!How many liters of a 70% alchole slolution must be added to 50% liters of a 40% alcohole solution to produce a 50% alcohol solution? ---------------- I assume it's 50 liters of 40% to start. That 50 liters has 60% water, = 30 liters of water (50*0.6). Add alcohol to make that 30 liters of water 50% of the solution. That will be a total of 60 liters of solution, 30 liters of water + 30 of alcohol. Add 10 liters of alcohol. --> 10 liters.
