그레이엄 법칙. He 1.0 L effuse 4.5 min Cl2 gas 1.0 L

그레이엄 법칙. He 1.0 L effuse 4.5 min Cl2 gas 1.0 L

 

 

He 1.0 L 분출에 4.5분 걸렸다면,

같은 조건에서 Cl2 1.0 L는 몇 분?

 

 

It took 4.5 minutes for 1.0 L helium to effuse through a porous barrier.

How long will it take for 1.0 L Cl2 gas to effuse under identical conditions?

> He의 몰질량 = 4.00 g/mol

> Cl2의 몰질량 = 70.91 g/mol

 

 

 

그레이엄의 법칙

v1 / v2 = (M2 / M1)^(1/2)

( 참고 https://ywpop.tistory.com/3478 )

 

 

 

(1 L/? min) / (1 L/4.5 min) = (4.00 / 70.91)^(1/2)

 

(1 L/? min) = (4.00 / 70.91)^(1/2) × (1/4.5)

 

? = 1 / ( (4.00 / 70.91)^(1/2) × (1/4.5) ) = 18.9468 min

 

 

 

답: 약 19분
