CRAWLSPACE YOU HAVE. There are two common ways to insulate a crawlspace. depending on the type of crawlspace. If there are pipes. and uninsulated ducts present, insulate the walls of the. crawlspace area. If there are no pipes in the area, insulate the floor above the space. SELECTING THE RIGHT.
If the mass of an apple is 100g on average and the mass of the earth is approximately 6.0 * 10^24kg how many apples would it take to equal the mass of the earth?
Example 5. How much do 1.00 X 10 12 (a trillion) gold atoms weigh in grams?1.00 X 10 12 atoms X 1 mol X 196.967 g = 3.27 X 10 â10 g 1 6.022 X 10 23 atoms mol Example 6. The mass of the earth is 5.98 X 10 24 kg. The mass of a baseball is 145 g.ust as a dozen apples is 12apples, a mole of apples is 6.022 X 10 23 apples. A mole of iron atoms is 6.022 X 10 23 iron atoms. Amole of water molecules is 6.022 X 10 23 water molecules.The NIST 2007 value of Avogadro's number is 6.022 141 79 Â± 0.000 000 30 X 10 23 mol â1.
