Find the pOH of a solution made by dissolving 10.4g of HCl in a 500mL solution of water

The pOH of a solution : 13.756

Mass HCl=10.4 g

mol HCl (MW=36.5 g/mol) :

Volume of HCl = 500 ml = 0.5 L

HCl ⇒ H⁺ + Cl⁻

[H⁺]=[HCl]=0.57 M

pH= - log[H⁺]

pH=-log[0.57]=0.244

pH+pOH=14

pOH=14-0.244

pOH=13.756

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
