  6. 4 sie 2024 · To convert grams to moles, start by multiplying the number of atoms by the atomic weight for each element in the compound. Then, add all of your answers together to find the molar mass of the compound.

  7. 7 wrz 2024 · The atomic mass of C is 12.01, and the atomic mass of O is 16.00. The formula mass of CO 2 is: 12.01 + 2 (16.00) = 44.01. Thus, one mole of CO 2 weighs 44.01 grams. This relation provides a conversion factor to go from grams to moles. Using the factor 1 mol/44.01 g: moles CO 2 = 454 g x 1 mol/44.01 g = 10.3 moles.
