A vinegar company has 10,000 galons of vinegar with the same comcentration as your unknown solution (mass percent acetic acid of .74%) This vinegar cannot be sold because its too weak, but the plant manager doesn't want to discard it. The company has another batch that is 9.5% acetic acid by mass. Calculate how many gallons of the strong vinegar would need to be added to the 10,000 gallons of the weak vinegar to obtain a solution that is the appropriate 5.10% acetic acid by mass.
