Use each of the two methods of buffer preparation to make a 1.0 M buffer with a 1:2 conjugate ratio (base:acid). Select the best answer from the dropdown for each method. Method 1: Weak base + conjugate acid. How many moles of NH4NO3 should be added to a 100 mL solution of 1.0 M NH3 to achieve the desired concentration and conjugate ratio? Method 2: Weak base + strong acid. A solution of HCl is added to 100 mL of 2.0 M NH3. What concentration of HCl should be used to achieve the desired concentration and conjugate ratio in the buffer while only using 100 mL of strong acid?
