Final answer:
The question involves chemistry-related data table completion by calculating the molecular mass or formula mass of chemical compounds from given elemental quantities and average atomic masses.
Step-by-step explanation:
The question pertains to creating and completing data tables based on chemical compounds and their respective atomic masses. To do this, a combination of quantification and multiplication of given atomic masses are required. The data table will include elements, their quantities, and the total molecular or formula mass calculated from these quantities and the average atomic masses of each element.
For example, to calculate the molecular mass of a compound, multiply the quantity of each element by its average atomic mass (amu) and sum the results to get the molecular mass. So, if a molecule consists of 1 carbon, 1 hydrogen, and 3 chlorine atoms, the molecular mass would be calculated as (1 x 12.01) + (1 x 1.008) + (3 x 35.45) = 119.37 amu.
For another compound, say, with 1 sodium (Na) and 1 chlorine (Cl), the formula mass is calculated as (1 x 22.99) + (1 x 35.45) = 58.44 amu. These calculations form the essence of understanding molecular and formula mass in chemistry, which is vital for many applications like stoichiometry and understanding the properties of compounds.
