Answer:

C_{21} H_{23} NO_{5}

Explanation:

First thing is we have assume all the percents are grams so we have

68.279g C, 6.2760g H, 3.7898g N, and 21.656g O

Now convert each gram to moles by dividing the the molar mass of each element

68.279g/12.01g= 5.685 moles of C

6.2760g/1.01g= 6.214 moles of H

3.7898g N/14.01g= 0.271 moles  of N

21.656g O/ 16.00g= 1.354 moles of O

Now to find the lowest ratios divide all the moles by the smallest number of moles you found, in our case, the smallest moles is 0.271 moles of N so divide everything by that....

5.685 moles/0.271 moles ------> ~21 C

6.214 moles/0.271 moles --------> ~23 H

0.271 moles  / 0.271 moles  ---------> 1 N

1.354 moles/ 0.271 moles ----------> ~5 O

So the empirical formula is C21H23NO5 C_{21} H_{23} NO_{5}

A gas has a volume of 2,280 ml. at 30.0C and 808 mm. pressure. Calculate its volume at standard temperature and pressure.
White raven [17]

Explanation:

Which statement best evaluates the effectiveness of the conclusion

paragraph?

Thesis Statement: My future job must include human interaction, a

nontraditional workspace, and teamwork.

Main Points:

1. Work with people

2. Work in a nontraditional workspace

3. Work in a place where coworkers share ideas

Conclusion: In the end, my future job will be one that allows me to

collaborate with my coworkers in dynamic and nontraditional

workspaces. If I am forced to sit behind a desk I will be extremely bored. Furthermore, I will be less productive if I am forced to work alone without the chance to discuss ideas with my coworkers. So the next time an adult asks me what I want to do when

I grow up, I will tell them a job without a desk, in an office full of

people. That's my dream job!

A. The conclusion is effective because it presents interesting information not addressed in the body paragraphs.

B. The conclusion is ineffective because it does not restate the thesis in a new way.

C. The conclusion is effective because it restates the thesis, summarizes the main points, and includes a satisfying close.

D. The conclusion is ineffective because it fails to leave the reader with a thought-provoking question.Which statement best evaluates the effectiveness of the conclusion

paragraph?

Thesis Statement: My future job must include human interaction, a

nontraditional workspace, and teamwork.

Main Points:

1. Work with people

2. Work in a nontraditional workspace
