First, convert grams to moles by dividing 8.5 by the molar mass of NH₃ (N=14,H=1)
14+1+1+1=17
8.5/17=.5 moles NH₃
Multiply .5 by the conversion factor of moles to L (22.4)
.5*22.4=11.2 L NH₃
11.2 is just 11.21 rounded down, so your answer is C) 11.21 L

8.5/17=.5 moles NH₃

Multiply .5 by the conversion factor of moles to L (22.4)

.5*22.4=11.2 L NH₃

11.2 is just 11.21 rounded down, so your answer is C) 11.21 L
