10 g is 10,000 mg and in 1 liter that would be 10,000 ppm. You need to have a volume in order to express the mass as ppm. In other words, 10 g NaCl cannot be expressed as parts per million unless you have the volume that it is in. If it's in a liter, then you will have 10,000 ppm.
10 grams = 10 000 000 micrograms (ppm)
