Hello soo im having a problem, i shot in raw a picture for a contest, days ago i asked a question about this. However, now that I finally took the shot and it was in B&W with the camera and also edited in lightroom B&W the image when i export it and set it to 300resolution dpi and 12.0mp it comes out getting 5MB or 6mb and thats not enough for the contest since 9MB = 12 MP. I appreciate any help guys please.

I think you're forgetting compression. If you saved the photo in a format like JPEG, the data will be compressed, and that could easily account for the difference in size.
