1. The problem statement, all variables and given/known data If 5.0L of antifreeze solution (0.8 specific gravity) is mixed with 4L of water to make a 9.0 L mixture. what is the specific gravity of the mixture? 2. Relevant equations SG = density of substance / density of water 3. The attempt at a solution I am confused as in how to gain the density from the substance gravity. Is it given that the density is 1 g/cm^3 for water?
