help required in calculating the pH value of a .84 mols per litre solution of sulfuric acid. I understand that pH = -log 10 (2x 0.84), I am not very experienced with logs and need assistance as to which keys to press on the scientific calculator in relation to the logs. thank in advance.

Learn your calculator.

all are different.

put this in the Google Search window:

-log(2*.84)

When you type "-log(2*.84)" into the Google Search window, it will calculate the value for you. In this case, the pH value of a 0.84 mol/L solution of sulfuric acid is approximately 0.255.

To calculate the pH value of a sulfuric acid solution with a concentration of 0.84 mol/L using a scientific calculator, you can follow these steps.

1. Enter the scientific calculator mode.

2. Look for the "log" or "log10" function on your calculator. It is usually denoted by the word "log" or the symbol "log" or "log10" on the calculator keypad.

3. Enter the value inside the parentheses: (2 * 0.84)

4. Multiply the value inside the parentheses: 2 * 0.84 = 1.68

5. Key in the negative sign symbol in front of the multiplication result: -1.68

6. Press the "log" or "log10" button on your calculator.

The calculator will then calculate the logarithm result for you. The final result will be the pH value of the solution.

If you don't have a scientific calculator, you can also use the Google search engine to calculate the logarithm:

1. Open the Google search engine in a web browser.

2. In the search bar, type the following: -log(2 * 0.84)

3. Press Enter or click the search button.

Google will give you the logarithmic result right on the search results page.

Remember, the pH value is calculated as the negative logarithm (base 10) of the concentration of hydrogen ions (H+) in a solution.

To calculate the pH value using a scientific calculator, follow these steps:

1. Enter "log" or "log10" on your calculator.
2. Multiply the concentration (0.84 mol/L) by 2.
3. Press the multiplication symbol (*) on your calculator.
4. Enter the result from step 2.
5. Press the equals (=) button to calculate the logarithm.
6. Finally, multiply the result by -1 to obtain the pH value.

For example, if you have a calculator with a separate log button:

1. Press the log button.
2. Enter 2 times 0.84, pressing the appropriate buttons for multiplication in between.
3. Press the equals (=) button to calculate the logarithm.
4. Multiply the result by -1 to obtain the pH value.

Alternatively, you can input the equation directly into the Google search bar as suggested.
