The maximum molecular mass ............ Atoms.

The maximum molecular mass of a compound is determined by the number and type of atoms it contains. To calculate the maximum molecular mass, you need to know the molecular formula of the compound.

Here's how you can determine the maximum molecular mass of a compound:

1. Start by identifying the molecular formula of the compound. The molecular formula provides information about the types and quantities of atoms present in the compound.

2. Determine the atomic mass of each element in the compound. The atomic mass is the average mass of an atom of a specific element, expressed in atomic mass units (amu). You can find the atomic mass of elements on the periodic table.

3. Multiply the atomic mass of each element by the number of atoms present in the compound, as indicated by the molecular formula.

4. Sum up the resulting values from step 3 to calculate the maximum molecular mass of the compound.

Keep in mind that the maximum molecular mass represents the mass of the compound with the highest possible number of atoms. This assumes that all the atoms are the heaviest isotopes of each element.

For example, consider the compound water (H2O). The molecular formula indicates that there are two hydrogen atoms (H) and one oxygen atom (O). The atomic mass of hydrogen is approximately 1 amu, and the atomic mass of oxygen is approximately 16 amu. By multiplying the atomic masses by the respective number of atoms and summing them up, you get the maximum molecular mass of water as 1 x 2 (hydrogen) + 16 x 1 (oxygen) = 18 amu.
