Answer:
HfCl3
Explanation:
Step 1: Find the compounds relative atomic mass
Step 2: Divide the percentage given by the relative atomic mass
Hf = 62.2/178.5 CI = 37.4/35.5
Hf = .348 CI = 1.054
Step 3: Divide every given number by its lowest ratio. (0.348)
Hf - .348/.348 CI - 1.054/.348
Hf= 1 CI = 3
This means, the empirical formula for this compound would end up being
HfCI3.
Hope this helps!
