JPEG since it compressed well, and is supported by virtually all devices and programs. To have a look in detail at its advantages see the related questions.
Depends on the amount of megapixels, if 4MP then then 22888. If 22MP then 4161, photos compressed. If uncompressed 4MP is 2288 and 22MP is 416. Then there is all the MP's in between
It is not possible to convert a JPEG file into a RAW format file. This is because a RAW file is a lossless recording of all the data received by the camera from the sensor and a JPEG file is a lossey compressed file containing only a fraction of this information. For this reason, the JPEG file would not contain enough data in order to recreate the amount required to generate a RAW file. RAW files can only be created directly by a camera as the image is recorded.
JPEG stands for Joint Photographic Expert's Group. It is a processed image format that uses compression to save space.
