Given information
Samples of several compounds are decomposed, and the masses of their constituent elements are listed here. Calculate the empirical formula for each compound.
Step-by-step explanation
Step 1.
Empirical formula is the simplest whole number ratio of atoms or elements present in the compound.
Thus using the mass of the elements and their atomic mass we find the moles first.
Then their simplest ratio is found by dividing the mole by the smallest mole value.
Let us make a table to find the empirical formula as shown below:
Atoms | mass | Atomic mass | Simplest ratio | ||
