Its the power you need to raise 10 to to get the number. 

For example, Log10 of 100 is 2. That means you have to raise 10 to the power of 2 (in other words, square it) to get 100. 

Or the Log10 of 1000 is 3. So you have to raise 10 to the power of 3 (cube it) to get 1000. 

and the Log10 of 10 is 1. 

Obviously, the Log10 of most other numbers are not so tidy. 

So, your turn. What's the Log10 of a million? - that's it, 6 

• You must determine how many grams are in a tonne. You then must then use the 
  • molecular weight of carbon to determine the moles of carbon in that many grams
    • (i.e. (grams C)/(M.W. of C)). As there is one mole of Carbon in each mole of
      • carbon dioxide, then multiply the resulting moles of carbon by the molecular
        • weight of CO2 and you will have your answer. OR... One metric ton (tonne) of
          • of carbon is equivalent to approximately 3.66 metric tons of carbon dioxide

V = 4/3(pi)r^3 , r = 3/2 = 1.5
V = (4/3)(3.14)(1.5^3)
= 14.10
Now divide by 2 for 1/2 of the ball. 
V/2 = 14.10 = 7.05
