Answer:

$\huge{ \boxed{0.197 \: \text{moles}}}$

Step-by-step explanation:

The number of moles of ammonia can be found by using the formula:

n = (m)/(M)

where

m is the mass in grams

M is the molar mass in g/mol

n is the number of moles

From the question:

m = 3.360 g

M = 17.030 g/mol

$\therefore \: n = (3.360)/(17.030) \\ = 0.19728 \approx \: 0.197 \: moles\\$

We have the final answer as;
