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?
1 Mole = 6.02 x 1023 1 mole of atoms = 6.022 x 1023 atoms 1 mole of molecules = 6.022 x 1023 molecules Molar Mass: the mass (in grams) of one mole a particular substance There is a unique relationship between molar mass and atomic weight: Oxygenâs atomic weight is 16.00 amu. 1 mole of oxygen is 6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24g What is the molar mass (g/mole) of oxygen? 16.00 amu/oxygen atom x 1.661 x 10-24g/amu = 2.657 x 10-24 g/atom x 6.02 x 1023 atoms/mole =16.00 g/mole Molar mass (in grams) is always equal to the atomic weight of the atom! Molar mass (in grams) is always equal to the atomic weight of the atom! Examples: Atomic weight of carbon is 12.01amu Molar mass of carbon is 12.01 g/mol Atomic weight of helium is 4.00 amu Molar mass of helium is 4.00 g/mol Mole (mol): The number of particles (atoms or molecules) in a sample of element or compound with a mass in grams equal to the
