Step 1

Solution stoichiometry involves the calculation of concentration of solutions in the given conditions of volumes, moles etc.

 

Step 2

Solution stoichiometry is mainly based on the calculation of moles and volumes. These two values are used to calculate the molarity of solution. The relation between moles, volume and molarity is as given below;

Moles of solute
Molarity
volume of solution in L
Mass of solute in g
Moles
Molar mass of solute (g/mol)
