epm to ppm. 2.2 epm HCO3^-의 ppm

epm to ppm. 2.2 epm HCO3^-의 ppm

 

 

2.2 epm의 HCO3^- 농도를 ppm으로 환산하면 얼마인가?

 

---------------------------------------------------

 

▶ equivalents per million (epm)

1 ppm = 1 mg/L 이듯이,

( 참고 https://ywpop.tistory.com/5345 )

 

1 epm = 1 meq/L

 

 

 

▶ equivalent weight × epm = ppm

(mg/meq) × (meq/L) = mg/L

( 참고 https://www.rigworker.com/calculation-formulas/chemicalepm-to-ppm-conversion.html )

 

 

 

HCO3^-의 몰질량 = 61.02 g/mol 이고,

HCO3^-의 당량수 = 1 eq/mol 이므로,

( 참고: 당량수 https://ywpop.tistory.com/4105 )

 

HCO3^-의 g당량수를 계산하면,

(61.02 g/mol) / (1 eq/mol) = 61.02 g/eq

 

 

 

ppm = equivalent weight × epm

= (61.02 mg/meq) × (2.2 meq/L)

= 134.24 mg/L

= 134.24 ppm

 

 

 

답: 134 ppm

 

 

 

 

[참고] Equivalent per million. epm

> An equivalent weight of an ion or salt per 1 million grams of solution or soil.

> For solutions, equivalents per million (e.p.m.) and milliequivalents per liter (meq/L) are numerically identical

if the specific gravity of the solution is 1.0 as it is for freshwater at 20℃.
