Answer:
The answer to your question is: 167960 milligrams
Explanation:
Data
milligrams = ?
9.88 moles of NH₃
Process
1.- Calculate the molecular mass of NH₃
N = 14 g
H = 3 x 1 = 3
total = 14 + 3 = 17
2.- Use the mol definition to find the grams of NH₃
17 g of NH₃ ---------------- 1 mol
x --------------- 9.88 moles
x = (9.88 x 17)/1
x = 167.96 g
3.- Convert grams to milligrams
1 gram ---------------- 1000 milligrams
167.96 gram ------ x
x = (167.96 x 1000) / 1
x = 167960 milligrams Result
