Answer:
Just add what they equal to hope this helps :)
Explanation:
Answer:
9
Explanation:
n-factor of NaOH = 1
OH⁻ concentration = Normality of NaOH
= Molarity x n-factor
= 10⁻⁵ x 1
= 10⁻⁵
Now, pOH = -㏒(OH⁻)
pOH = -㏒(10⁻⁵)
pOH = 5
We know pH + pOH = 14
pH = 14 - 5 = 9
∴pH of 10⁻⁵M NaOH is 9
2,3,5-trimethylhexane
C9H20
Molecular weight= 128.5g/mol
CH3-CH(CH3)-CH(CH3)-CH2-CH(CH3)-CH3
