Explanation:
Methanol's molecular weight:
Methanol's heat of vaporization:
Ideal gas heat capacity (Cp):
where R is the gas constant
The heat needed to vaporize and bring the gs to 210°C is:
First you calculate the pOH of the solution:
pH+ pOH = 14
3.25 + pOH = 14
pOH = 14 - 3.25
pOH = 10.75
<span>Concentration of [OH]</span>⁻<span> in solution:
</span>
[ OH⁻ ] =
[ OH⁻ ] = 10^ - 10.75
[OH⁻] = 1.778 x 10⁻¹¹ M
hope this helps !
