Answer to Problem 154A

The percent composition and mass of elements present in the compound should be known.

Explanation of Solution

The rules for determining empirical formula is given as follows:

  • Determine the mass of elements in given compound.
  • Calculate number of moles using molar mass of each compound or element.
  • Divide each number of moles by smallest number of mole value calculated in second step.
  • Round the value calculated in step 3 to nearest whole number.

Thus, to find out an empirical formula for an unknown compound, the mass of the elements present in the compound should be known.
