Depends on resolution -- maybe if you state megapixels of camera maybe someone will calculate it for you -- though many cameras indicate in the viewfinder how many pictures can be taken on the space remaining on a card.

If yours does, put in a blank card and see what the camera suggests -- though the number will reduce or increase if you change the setting which sets the picture-taking quality (resolution) .
