Josh prepares a solution by mixing sodium nitrate with water. To calculate the molarity of the solution, josh should calculate the moles of which substance,and why?
There
are a number of ways to express concentration of a solution. This includes
molarity. Molarity is expressed as the number of moles of solute per volume of
the solution. Josh should calculate the moles of the sodium nitrate by dividing the mass with the molar mass of sodium nitrate. This is because it is the solute in this problem.
