Question 1 of 17

Please upload (in PDF format) a picture of your gas collection apparatus (step 6 in the lab document and Figure 4 in the lab manual procedure). To receive credit, your ringstand, graduated cylinder, beaker, all tubing, flask, etc., as well as the oxygen bubbles, must be clearly visible in the picture, as well as clear label with your name, the lab title (with Experiment number), and the date in clear view. This must be a single picture in a PDF file in order to receive credit.

NOTE: If your document is not clear, organized, and properly labeled, or any part of it is unclear to your instructor, you will not receive credit

Question 3 of 17

Converting to Kelvin

The goal for Experiment 1 in Lab 9 is to find the percentage of hydrogen peroxide in the solution. This can be found by using your data and the ideal gas law equation. To determine percentage, you need to find out how many moles of hydrogen peroxide are present, which means you need rearrange PV=nRT to solve for n, and you need to plug in your known values for P, V, R, and T. But, you have to use proper units for the equation to work.

So, show your calculations from Experiment 1 for converting your temperature (T) to Kelvin.

NOTE: All work must be shown. Skipping steps or lack of clarity in steps will result in loss of points. All units must be properly labeled. Be sure to click on "Show/Hide Rich Text Editor" above your answer box so you can include subscripts, superscripts, etc. as needed. If your formatting is unclear (be careful, then about copy/pasting--it is much wiser to type your answer directly into the answer box rather than copy/pasting!), you will not receive credit.

Converting to atm

The goal for Experiment 1 in Lab 9 is to find the percentage of hydrogen peroxide in the solution. This can be found by using your data and the ideal gas law equation. To determine percentage, you need to find out how many moles of hydrogen peroxide are present, which means you need rearrange PV=nRT to solve for n, and you need to plug in your known values for P, V, R, and T. But, you have to use proper units for the equation to work.

So, show your calculations from Experiment 1 for converting your pressure (P) to atm. (If you obtained the pressure originally in atm without converting, then convert atm to mmHg to demonstrate you know how to do this conversion.)

NOTE: All work must be shown. Skipping steps or lack of clarity in steps will result in loss of points. All units must be properly labeled. Be sure to click on "Show/Hide Rich Text Editor" above your answer box so you can include subscripts, superscripts, etc. as needed.

But, you have to use proper units for the equation to work.

So, show your calculations from Experiment 1 for converting your volume (V) from milliliters (mL) to liters (L).

NOTE: All work must be shown. Skipping steps or lack of clarity in steps will result in loss of points. All units must be properly labeled.

Explanation / Answer

To calculate all the incognitas of the ideal equation of the gases the values of at least four of the five incognitas are needed. One of them is the constant of the gases, and for this reason its value is always the same. We need the volume, the pressure, the number of moles, or quantity of substance and the temperature. What we can do, so that the units are always the same, will be to put all the terms of the incognitas in terms of the value of the gas constant.
