PH = -log[H3O+]
Solving for [H3O+] gives
[H3O+] = 10^-pH
= 10^-3
or 1x10^-3 M

Answer: Missing data related to question is attached below
If the KH,CH4 = 1.42 * 10^-3 mol/L atm
answer:
0.88 atm
Explanation:
P1 = 20 psi
aqueous concentration of methane in closed bottle = 20 ppm
20 ppm = 20 / 1000 ( gram / Kg ) = 0.020 gram/kg = 0.020 g/liter
molar mass of methane = 16 gram/mol
<em>next : convert mass conc to molar conc </em>
Cm = 0.020 / 16
Cm = 1.25 * 10^-3 mol/L
Given that KH,CH4 = 1.42 * 10-3 mol/L atm
Applying equilibrium relationship
Cm = ( KH,CH4 ) ( partial pressure of methane )
hence partial pressure of methane
= Cm / ( KH,CH4 ) = 1.25 * 10^3 / (1.42 * 10^-3 ) = 0.88 atm
<span>2HI + Ca(OH)2 --> Cal + 2H2O. According to stoichiometry, 2 moles of HI reacts with 1 mole of Ca(OH)2. Therefore, 1.2 moles of HI will react with = 1.2/2 = 0.6 moles of Ca(OH)2. Hope this helps.</span>
