The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Calcium Carbonate, or 100.0869 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles Calcium Carbonate and gram.
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
