The answer entirely depends on multiple factors. How large of an image are you taking and how large is the memory card in storage size?
I would say the average from personal experience would be about 500.
But for much better detail here is a chart from sandisk a maker of memory cards.

The average photo is 0.293 MB. Converted to GB, 0.293MB is 0.0002861328125GB.
To find out how much a 8GB memory card can hold, simply divide 16 by 0.0002861328125. The answer is 27959.05.
Therefore, a 8gb memory card can hold approximately 27 959 pictures, assuming the average photo size is 0.293 MB.
However, keep in mind that memory cards are never exactly 8gb, and will most often be slightly less (like 7.6 GB). Also, HD photos will take up more space, whereas lower resolution photos will take less space.
It actually depends on the resolution/pixel setting you will use to take pictures.
A 8 GB can hold 40 pics
Depends on the size of the pictures.
That is way to small of an sd card for that type or camera. You will probably be able to take only a few pictures. Try to at least get a 256mb sd card, that will hold a lot more pictures.
It depends on the quality of pictures you take, but with a 2GB card you should be able to store around 500 or 600 photos.
It depends what the capacity of the SD card is. They come in various capacities rated in megabytes or gigabytes e.g. 256mb or 1gb. It also depends on the size of the image. If you have a high quality camera then you could be saving pictures that are about 2-3mb in size. You can roughly work it out by dividing the capacity of your SD card by 3!
The reason the phone reads 1 gigabit of memory on the sd card when it is a 4 gigabit sd card is because it needs to be reformatted.
The memory that is found on a micro SD card is most commonly gigabytes. There are also micro SD card that are megabytes. The megabytes are smaller than the gigabytes.
depend on the picture size and their quality if you are saving .png format picture than it you can save upto 10000 pics on 2 GB or more.
The manual for your camera should tell you what the maximum capacity SD card you can use with your camera is. If the SD card is the same physical size as the 16 GB card the camera comes with, it should be fine to use.
about 300 in a 2 gb micro sd card
As many as you want or about 150 songs.
4 million minutes
It depends how many photos you will take. But you should get a bit more of GB if its a sD card. Ebay has 64 GB micro sD cards for around $18.00.
Your 3DS should have came with a 2 GB SD card. If you have an SD card reader on your computer, plug in your card to your computer, then put whatever music you want on the sd card. Plug the sd card back into your 3DS, and turn on the music channel.
