Question

How many milligrams are in 9.88 moles of NH₃? (Show Work)

Answer 1

The answer to your question is: 167960 milligrams

Step-by-step 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
