how to I convert 10mg/L (10ppm) of nitrate (NO3-) to molar mass of nitrate? Ç Chapter 10 part 1: concentration units As we have learned throughout this class, water contaminants can be harmful to the human body and the environment. There is an exact amount of how much nitrate can be present in drinking water before it becomes unsafe. The U.S. EPA has a standard of 10 milligrams of nitrate per liter of water (mg/L), which is the same as 10 ppm. Anything at or below 10mg/L is considered to be safe for humans to drink. If we were to consume more than the standard level of nitrate it can cause a lot of health concerns, like weakness, dizziness, and an excessive heart rate. Problem: What is the molar mass of Nitrate at 10ppm? the same problemljust worded differently Nitrate (NO3-) I 1mg/L-1ppm convert 10ppm of (NO3-) into molar mass of (NO3-)
