Question

What volume of ammonia (NH3) will react completely with 25.0 liters of O2? 4 NH3 + 3 O2 ---> 2 N2 + 6 H2O

Answer 1

18,75 litres

Step-by-step explanation:

4 NH3 + 3 O2 ---> 2 N2 + 6 H2O

n (NH3) : n (O2) = 4 : 3

<=>

V (NH3) : V (O2) = 4 : 3

Hence, V(O2) = 3 × V (NH3) ÷ 4 litres

V(O2) = 3 × 25.0 ÷ 4 litres

V(O2) = 75 ÷ 4 litres

V(O2) = 18,75 litres
