How do I do this ? What was AMU again?

Answer 1

Answer

n=4

Procedure

Data

Sulfur has an atomic mass of 32.065 u

Fluorine has an atomic mass of 18.9984 u

To solve this problem we need to find the number of atoms of fluorine, this can be done using an equation as follows

$108.01=32.065+18.9984x$

Solving for x we have

$x=\frac{108.01-32.065}{18.9984}=3.99\approx4$

Hence as we can't have a decimal atom we consider 4 atoms of fluorine.
