Answer:
14.512g
Explanation:
Using the expression
mole = Number of molecules/6.022 x 10^23
mole of Fluorine = 2.30 x10^23/6.022 x 10^23
= 0.3819 mol
However,
mole = mass / molarmass
Mass of Fluorine = mole of Fluorine/ Molarmass of Fluorine
Molarmass of Fluorine = 18.998 x 2 = 37.996 g/mol
Mass of Fluorine = 0.3819mol/37.996g/mol
= 14.512g
