Answer is: volume of ammonia gas is 7,392 L

Chemical reaction: 6NO + 4NH₃ → 5N₂ + 6H₂O.

m (NO) = 15,0 g.

V (NH₃) = ?

n (NO) = 15,0 g : 30 g/mol.

n (NO) = 0,5 mol.

from reaction: n (NO) : n (NH₃) = 6 : 4

0,5 mol : n (NH₃) = 6 : 4.

n (NH₃) = 0,33 mol.

V (NH₃) = 0,33 mol · 22,4 L/mol (molar volume at STP).

V (NH₃) = 7,392 L.

n - amount of substance.
