Molecular Weight Worksheet. The formula weight of a substance is the sum of the atomic weights of each atom in its chemical formula. 1) cl 2 2) koh 3) becl 2 4) fecl 3 5) bf 3 6) ccl 2 f 2 7) mg(oh)
Molecular weight and mole conversion **all answers should be in correct number of significant digits.** i. 1) cl 2 2) koh 3) becl 2 4) fecl 3 5) bf 3 6) ccl 2 f 2 7) mg(oh) Web formula and molecular weights.
Web to the right of the element symbol on most periodic tables. E.g., h 2 o, c 2 h 6, n 2 o 4, nh 3. Chemical analyses commonly produce weight percent elemental data of the elements.

The word molar is obtained from the word moles, and therefore, the molar. Determine the number of moles of compound and the number of moles of each type of atom in each of the following: (a) 25.0 g of propylene, c.
