#### Answer:

10.5263 moles

#### Explanation:

Fluorine has atomic mass of 18.998403 g/mol rounding of we consider 19 g/mol

So,

In 19 g fluorine is 1 mole

so in 200g fluorine

which equals 10.5263 moles

Assume that:

n = number of moles

m = mass of substance

M = molar mass (same as atomic weight on periodic table)

200 grams of fluorine (m) has been provided for you.

The molar mass (M) of fluorine is 19.0 g/mol.

Therefore, the number of moles (n) for fluorine is:

[n = 200 grams

Note: the answer is rounded to 3 significant figures

There are 10.5 moles in 200 grams of fluorine.
