Answer:

HfCl3

Explanation:

Step 1

Divide the percent by mass of each element by its relative atomic mass

Hf- 62.2/178.5, Cl-37.4/35.5

0.348, 1.054

Step2

Divide through by the lowest ratio

0.348/0.348, 1.054/0.348

1, 3

Therefore the empirical formula is HfCl3

kiruha [24]
Since Titan orbits roughly along Saturn's equatorial plane, and Titan's tilt relative to the sun is about the same as Saturn's, Titan's seasons are on the same schedule as Saturn's—seasons that last more than seven Earth years, and a year that lasts 29 Earth years.
