Question
Chapter 8.7, Problem 8.36YT
Interpretation Introduction
Interpretation:
- The water diary has to be examined.
- In which area does the water use depend upon dissolved ionic and molecular compounds have to be found.
- Whether the water uses add solutes to the water or not has to be found.
Concept Introduction:
Solubility: At molecular level, solubility is controlled by the energy balance of intermolecular forces between solute-solute, solvent-solvent and solute-solute molecules.
‘Like dissolves like’- polar compound get dissolves in polar solvent and non-polar compound dissolves in non-polar solvent.
Solute: A concentrated solution has large amount of solute in a small amount of solvent.

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
