# Problem: A chemist decomposes samples of several compounds; the masses of their constituent elements are listed. Calculate the empirical formula for each compound.1.245 g Ni, 5.381 g I

###### FREE Expert Solution

We need to get the moles of each element in the compound.

The atomic masses are 58.69 g/mol Ni and 126.9 g/mol I.

= 0.02121 mol Ni

= 0.0424 mol I

Divide the number of moles of each by the smallest value.
