1.34 L H2 reacts with sufficient N2 at constant temperature and pressure

1.34 L H2 reacts with sufficient N2 at constant temperature and pressure

 

 

Ammonia is produced by reacting hydrogen gas and nitrogen gas.

If 1.34 L of hydrogen gas reacts with sufficient nitrogen gas at constant temperature and pressure, what mass of ammonia gas is produced?

N2 + 3H2 → 2NH3

 

 

 

H2 : NH3 = 3 : 2 계수비(= 부피비) 이므로,

H2 : NH3 = 3 : 2 = 1.34 L : ? L

? = 2 × 1.34 / 3 = 0.893 L

 

 

 

STP 조건이라면,

0.893 L × (1 mol / 22.414 L) × (17 g / 1 mol) = 0.677 g

답: 0.677 g
