Adding up all of the _____ of all of the individual atoms within one molecule of a compound will determine the molecular mass of the compound.
A. protons
B. atomic numbers
C. electrons
D. atomic masses
Answer (2)
Molecular mass is determined by summing the properties of individual atoms in a molecule.
Consider the definition of molecular mass.
Molecular mass is the sum of the atomic masses of all atoms in the molecule.
Therefore, the answer is D) atomic masses. $\boxed{D}
Explanation
Understanding the Question The question asks what property of individual atoms, when summed within a molecule, determines the molecular mass of the compound.
Listing the Options The options are: A) protons B) atomic numbers C) electrons D) atomic masses
Recalling the Definition of Molecular Mass Molecular mass is the sum of the atomic masses of all atoms in the molecule.
Determining the Answer Therefore, the answer is D) atomic masses.
Examples
Understanding molecular mass is crucial in chemistry, especially when calculating the amounts of reactants and products in a chemical reaction. For example, if you're synthesizing a new drug, knowing the molecular mass helps you determine how much of each ingredient to use to achieve the desired product yield. This ensures accuracy and efficiency in chemical processes, preventing waste and optimizing results.
The molecular mass of a compound is determined by summing the atomic masses of all its individual atoms. The correct answer is D) atomic masses, as they directly contribute to the calculation of molecular mass. Understanding this concept is crucial in chemistry for accurate calculations in various applications.
