What is the molarity of the concentrated ammonia (NH3)?

28% NH3 시약(d 0.898, FW 17)의 몰농도

 

 

The label on the bottle of concentrated ammonia says that

the contents are 28% (by mass) NH3 and has a density of 0.898 g/mL.

 

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

 

 

= (28 / 100) × (1 / 17) × (0.898) × (1000)

= (28) × (1 / 17) × (0.898) × (10)

= 14.79 mol/L

 

 

 

or

Molarity = (wt% / molar mass) × density × 10

( 참고 https://ywpop.tistory.com/4241 )

 

= (28 / 17) × 0.898 × 10

= 14.79 M
