Let the units drive the solution: #grams x (1 mole/...
Molarity. This is a two step calculation. First you must find the number of moles of solute in your solution. Then divide the number of moles solute by the volume of solution expressed in L. 1 mol NaCI g solute) ( mol Naci g Nai M=(- mol NaCI L solution M An alternate solution allows you to perform the calculation of molarity in a single step by starting with the ratio of grams of solute to the volume of solution....
