Help Please On Lewis Dot Diagram Problem

How would I go about making a Lewis Dot Structure for Gasoline? Which, according to a quick google search is C7H17?

I just can't figure out how this works, and yet it should, shouldn't it? How can I create an electron dot diagram for it? I always find that I have an extra Hydrogen molecule off in space.

And is C7H17 actually some sort of chemical compound? Or did I mess up on the original question:

Quote:Write a Lewis Dot Diagram for a chemical compound that is 83.2% Carbon, and 16.8% Hydrogen.

According to my calculations, it is C7H17, right? Now... How do I write a Lewis Dot structure for it?

If anyone can help my out on this, It'll be much appreciated. Thanks in advance.

I hate to break it to you, but just saying gasoline in the world of chemistry is highly vague. But generally speaking (for the purpose of high school/general chemistry) use C8H18. I think you'll find it fits much easier. It's about 84% carbon.
