A reaction requires 22.4 L of gas at STP. You have 25.0 L of gas at 101.5 kPa and 373 K. Which statement is true? Use the ideal gas law: PV = nRT where R = 8.31 L-kPa/mol-K

A. You will have excess gas for the reaction
B. You do not have enough gas for the reaction
C. Given this information, you cannot tell if you have enough gas for the reaction
D. You will have enough gas for the reaction

pH = 11.3

Explanation:

From the question given above, the following data were obtained:

Concentration of hydronium ion [H₃O⁺] = 4.950×10¯¹² M

pH =.?

The pH of a solution is defined by the following equation:

pH = –Log [H₃O⁺]

Thus, with the above formula, we can obtain the pH of the solution as follow:

Concentration of hydronium ion [H₃O⁺] = 4.950×10¯¹² M

pH =.?

pH = –Log [H₃O⁺]

pH = –Log 4.950×10¯¹²

pH = 11.3
