Explanation:
I just did the 1st page. Gimme a min and I'll do the second.
From ideal gas equation, that is PV =nRT
P=nRT/V
n is the number of moles
the molar mass of CH4 =12+4=16
R is the gas contant (0.0821 atm/mol/k)
n= 6.022/16=0.376 moles
P={(0.376 moles x 0.0821 atm/mol/k x 402k) /30.0L} =0.414 atm

Explanation:
Let us recall that;
[H^+] [OH^-] = 1 * 10^-14
Where;
[OH^-] = 1 x 10^-11
Then;
[H^+] = 1 * 10^-14/1 x 10^-11
[H^+] = 1 * 10^-3
pH = -log [H^+]
pH = -log(1 * 10^-3)
pH = 3
Also;
pH + pOH = 14
pOH = 14 - pH
pOH = 14 -3
pOH = 11
