Final answer:
The question pertains to calculating the molecular mass of a compound in Chemistry, a concept encountered in High School. The molecular mass is found by multiplying the average atomic mass of each element by its quantity and summing the results, which for CHCl3 is 119.37 amu.
Step-by-step explanation:
The question provided involves calculating the molecular mass of a chemical compound, indicating that it is a Chemistry question, typically encountered at the High School level. The various tables described in the question all pertain to the concept of molecular mass, which is the sum of the average atomic masses of all the atoms in a molecule. In chemistry, molecular mass is often calculated using the formula mass (amu) of individual elements multiplied by the quantity of each in the molecule, followed by summing these values.
For example, to calculate the molecular mass of CHCl3, which is also known as chloroform, we multiply the average atomic mass of each element by its quantity in the molecule and then add these subtotals together. The molecular mass is calculated as follows: C (12.01 amu) × 1 + H (1.008 amu) × 1 + Cl (35.45 amu) × 3. This gives the subtotals of 12.01 amu for C, 1.008 amu for H, and 106.35 amu for Cl (3 × 35.45 amu). The sum of these subtotals yields the molecular mass of chloroform, which is 119.37 amu to two decimal places.
