Can you kind Basilers help me out with my Chem question?

What's the total number of valence electrons in ketene (C2H2O)? My answer was 10, but apparently it's wrong.

The structure of Ketene looks like this, according to my assignment: http://i128.photobucket.com/albums/p179/lily2040/Ketene.jpg?t=1296063537

I need the answer to this question to move onto the next ones, so I could really use some help. No one on Yahoo really replies and I can't find any results on Google.

16.
Hydrogen only makes 1 bond = 1 electron in its valence shell.
Double bonds are 4 electrons since each bond is 2 electrons each.
4 valence electrons for oxygen.

Yup, it's 16. Turns out I counted each Hydrogen as 2.

Thanks, everyone.

16.
The 2 carbons each have 4 valence electrons, oxygen has 6, and the 2 hydrogens each have 1.

4? Don't you just count the dots.

edit: nvm I think its 16, took chem like 4 years ago.

Off the top of my head, if i think it's asking for what you're asking, the answers 16.
