									                  Metric Conversions
grams (g) is used for mass (weight)
liters (l) is used for volume
meters (m) is used for distance

We will use a problem solving process
  called dimensional analysis (tracks).
Example      25.0 cg = _______ g
25.0 cg 1 g
            100 cg    = 0.250 g
Example 0.351 hl = _______ ml
0.351 hl 100,000 ml
             1 hl              = 35,100
  ml

Your turns - convert the following:
15.72 g = ______ mg 15.72 g = _____ kg
15.72 g       1000 mg
                  1g       = 15,720 mg
15.72 g        1 kg
                    1000g     = 0.01572 kg
       Converting Temperature

F = 1.8C + 32
C = (F-32)  1.8
                      Density = m  v
                             D = m/v
intensive property
  density is the same no matter size
50 grams of gold has the same density
 as 150 grams of gold.
Important density to remember
  water is 1.0 g/ml at 4 oC.
                  Density Problem
A substance has a volume of 1.74 ml
 and a mass of 20.0 grams. What is the
 density?
What is the substance? Use page 96 of
 your text.
                   Density Problem
One more to test your algebra:
What is the volume of ice in a container
 if the density is 0.920 g/ml and the
 mass is 58.39 g?
0.920 g/ml = 58.39 g
                    V          V = 63.5 ml
