0.25 N NaOH 300 mL + 0.5 N NaOH 150 mL 혼합 용액의 농도

0.25 N NaOH 300 mL + 0.5 N NaOH 150 mL 혼합 용액의 농도

 

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

 

(0.25 eq/L) * 0.300 L = 0.075 eq NaOH

(0.5 eq/L) * 0.150 L = 0.075 eq NaOH

( 계산 설명 http://ywpop.tistory.com/7787 )

 

 

(0.075+0.075 eq) / (0.300+0.150 L)

= 0.3333 eq/L

= 0.3333 N

 

 

답: 0.33 N
