<span>B. 100 g
Assuming that Ms. Bristol wiped off any condensation prior to making with mass measurements, the mass of the beaker and water (in solid, or liquid form), will remain constant. This is a simple demonstration of the law of conservation of mass. Since the beaker was closed, matter could neither enter, nor exit the beaker.</span>
Answer: Upper Case Alleles

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
