Answer:

C. 217.8 g

Explanation:

First, we find the weight of KF. notice they are 1:1 ratio. so the molar mass of K is 39.0983 and Fluorine is 18.998403

we add them together we get 58.09 g/mol

now to find the mass we do

[tex]\frac{58.096 Grams}{mol}[/tex] * 3.175 mol

mol and mol cancel out, we left with 58.096 grams * 3.75

if you multiply you get 217.86 grams.
