You are to prepare about 1 L of a solution which contains approximately 0.100 mole NaOH per liter. Before you begin, you should calculate the amount of saturated NaOH you will need for this solution. Assume that the saturated NaOH is approximately 3.5 M. Since the number of moles of NaOH will not change upon dilution, your calculation should be of this form: mol NaOH before dilution = mol NaOH after dilution mol NaOH before dilution = 3.5 M x ?? L mol NaOH after dilution = 0.100 M X ?? L ?? L (saturted NaOH) = (0.100 M x 1 L) / (3.5 M)

You are to prepare about 1 L of a solution which contains approximately 0.100 mole NaOH per liter. Before you begin, you should calculate the amount of saturated NaOH you will need for this solution. Assume that the saturated NaOH is approximately 3.5 M. Since the number of moles of NaOH will not change upon dilution, your calculation should be of this form:
mol NaOH before dilution = mol NaOH after dilution
mol NaOH before dilution = 3.5 M x ?? L
mol NaOH after dilution = 0.100 M X ?? L
?? L (saturted NaOH) = (0.100 M x 1 L) / (3.5 M)
