Answer:


\huge{ \boxed{28.42 \: g}}

Step-by-step explanation:

The number of grams or the mass of
NH_3 can be found by using the formula;


m = M * n

where

m is the mass in grams

M is the molar mass in g/mol

n is the number of moles

From the question;

n = 2.03 mol

Molar mass (M) of
NH_3 = 14 + (1×3) = 14 + 3 = 17 g/mol


\therefore \:m = 17 * 2.03 = 28.42 g
