Hope this answer can help you. Have a nice day!
The seven dots around flourine are the valence electrons
<em>V = 151 mL = 151 cm³</em>
<em>d = 0,789 g/mL = 0,789 g/cm³</em>
--------------------------------------
d = m/V
m = d×V
m = 0,789×151
<u>m = 119,139g</u>
1) 1.8 micrograms(least)
2) 1.8 grams
3) 1.8 kilograms(greatest)
