An automobile cooling system has a capacity of 17qt. Initially, the system contains a mixture of 2 gal of antifreeze and 9 qt of water. Water runs into the system at the rate of 1 gal/min and the homogeneous mixture runs out a petcock at the same rate. How much anti freeze remains in the system after 5 min?
First I converted the units but after that, I don't know how to solve it.
Concentration of a solute in a solvent
e.g. what is the concentration of salt solution in which we have 2 grams of salt per gallon of water? 2 grams per gallon, of course, not 2 grams per (gallon + 2 grams)
i think what is confusing you here is the fact that the solute and the solvent have the same units, gallons. but it works out if you think about it
