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.
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
