w/v % 농도. NaOH 12 g을 포함한 220 mL 용액

 

 

NaOH 12 g을 충분한 양의 물에 녹여 220 mL의 용액을 만들었다.

녹아있는 NaOH의 질량/부피 백분율 농도는?

 

 

What is the mass/volume percent (m/v) of NaOH in a solution

prepared by dissolving 12 g of NaOH

in enough water to make 220 mL of solution?

 

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

 

(12 g / 220 mL) × 100 = 5.45% (m/v) NaOH solution

[예제]

A student prepared a solution by dissolving 5.0 g of KI

in enough water to give a final volume of 250 mL.

What is the mass/volume percent (m/v) of the KI solution?

 

[풀이]

(5.0 g / 250 mL) × 100 = 2.0% (m/v) KI solution
