Problem 6P

If 5.0 L of antifreeze solution (specific gravity = 0.80) is added to 4.0 L of water to make a 9.0-L mixture, what is the specific gravity of the mixture?

Chapter 1 PHYS 1220 SI Units SI units are used for equations in the course o The SI unit for time is the second (s) o The SI unit for length is the meter (m) o The SI unit for mass is the kilogram (kg) Numbers can be simplified using scientific notation Units can be converted using a conversion factor Dimensional Analysis Density ρ=(m/v) Dimensional analysis when the dimensions of a quantity instead of the value are used to solve a problem; this is often used to check a problem Dimensions can be treated as algebraic symbols for example: o V=l*w*h each is a unit of length so volume is
