POH=4.22
pOH = -lg[OH⁻]
[OH⁻]=10^(-pOH)
[OH⁻]=10⁻⁴·²² = 6.0×10⁻⁵ mol/L
6.0×10⁻⁵ M

R in the equation is a gas constant. It is .0821 liters x ATM over Moles x degrees kelvin.
23 kilometers an hour or to be exact 23.07 kilometers an hour
Answer: 0.30 M
Explanation:
According to the neutralization law,
where,
= molarity of 
solution = ?
= volume of solution = 24.6 ml
= molarity of 
solution = 0.222 M
= volume of solution = 33.0 ml
= valency of = 21
= valency of = 1
Therefore, the molarity of the HCI solution is 0.30 M
