Question

Jawab pake caranya ya. Yang nomor 3 sama 4

Answer 1

3.)

4.)
M = (gram / Mr) × (1000/ ml)
M = (8,5 / 17 )×( 1000/500)
M = (8,5/17)×2
M = 17/17 = 1

OH = √(M × Kb)
=> √(1×1,8 × 10^-5)
=>√(18×10^-6)
=>(√18) × 10^-3

pOH= -log (OH)
=> -log ((√18) × 10^-3)
=>3 - log 18

pH= 14 - pOH
=>14 - (3-log √18)
=>11+log √18

semoga membantu:) ;)
