NH3 2.94 g excess NaClO NCl3 gram

 

 

If chlorine bleach is mixed with other cleaning products containing ammonia, the toxic gas NCl3(g) can form according to the equation:

3NaClO(aq) + NH3(aq) → 3NaOH(aq) + NCl3(g)

When 2.94 g of NH3 reacts with an excess of NaClO according to the preceding reaction, how many grams of NCl3 are formed?

 

 

 

> NH3의 몰질량 = 17.03 g/mol

> NCl3의 몰질량 = 120.37 g/mol

 

 

 

질량비로 계산하면,

( 참고: 질량비로 계산 https://ywpop.tistory.com/22115 )

 

NH3 : NCl3 = 17.03 : 120.37 = 2.94 g : ? g

 

? = 120.37 × 2.94 / 17.03 = 20.78 g

 

 

 

답: 20.8 g
