Answer:
380g
Explanation:
Given parameters:
Number of moles of Fluorine = 20moles
Unknown:
Mass of Fluorine = ?
Solution:
The number of moles is the unit of quantifying the amount of particles in a substance.
So;
Mass of a substance = number of moles x molar mass
Molar mass of F = 19g/mol
Now;
Mass of F = 20 x 19 = 380g
