A government laboratory wants to determine whether water in a certain city has any traces of fluoride and whether the concentration exceeds the recommended 5.50 ppm. A 5.00 g sample of this water is found to have 0.0000252 g of fluoride. What is the ppm, and should the water be declared safe for drinking?
