<u>Answer:</u> The pH of the solution is 1.022

<u>Explanation:</u>

pH is defined as the negative logarithm of hydrogen ion concentration present in a solution.

To calculate the pH of the reaction, we use the equation:

pH=-\log[H^+]

where,

[H^+]=9.49\times 10^{-1}mol/L

Putting values in above equation, we get:

pH=-\log(9.49\times 10^{-1})\\\\pH=1.022

Hence, the pH of the solution is 1.022

Answer:

1.27 atm.

Explanation:

The following data were obtained from the question:

Pressure (P) in torr = 968 torr

Pressure (P) in atm =...?

Thus, we can convert from torr to atm by doing the following:

Recall:

760 torr = 1 atm

Therefore,

968 torr = 968/760 = 1.27 atm

Therefore, 968 torr is equivalent to 1.27 atm.
