You will need to make various dilutions of potassium nitrate $(KN{O}_3).$ First, you need to make a $KN{O}_3$ solution at a concentration of $60m\frac{g}{L}N{O}_3-N($i$.$e$.,mg\frac{N}{L}).$

Calculate the mass of $KN{O}_3$ you will need to prepare $100mL$ of a primary standard solution of $60m\frac{g}{L}N{O}_3^{-}-N.$

Next you will need to make $50mL($final volume$)$ dilutions to create a calibration curve. For each concentration, determine the volume of standard solution to add and the volume of water to add.
