Answer:

190 grams

Explanation:

Find the molar mass of NaF

Na = 23.0

F = 19.0

23 + 19 = 42

Now use this dimensional analysis to show your work

4.5 mol NaF * ( 42.0 grams of NaF / 1 mol NaF)

Moles cancel out.

4.5 x 42.0 = 189

With sig figs, it is 190.

So the final answer is 190 grams in 4.5 moles NaF
