Question

In cell 2, create a formula to combine the item in A2 (CH-AD) and Inventory ID in B2 (2986) with no space between them, so that C₂ lists ________.

Answer 1

The molecular mass of CHCl3 is 119.37 amu, calculated by multiplying each element's average atomic mass by its quantity and summing the products, whereas the formula mass of NaCl is 58.44 amu following the same procedure.

Step-by-step explanation:

To calculate the molecular mass or formula mass of a compound, one must multiply the average atomic mass (amu) of each element by the quantity of each element present in a molecule and then sum the products. For instance, the molecular mass of CHCl3 (Chloroform) is determined by adding the subtotal amu values of C (1 x 12.01), H (1 x 1.008), and Cl (3 x 35.45), which results in 119.37 amu. Similarly, the formula mass of a compound like NaCl can be found by adding the subtotal amu values of Na (1 x 22.99) and Cl (1x 35.45), totaling 58.44 amu. These calculations are essential in Chemistry, particularly in studies involving stoichiometry and chemical reactions.
