What volume of 60.0 mM potassium maleate buffer, pH 6.5, would be needed to make 0.250 liters of 10.0 mM maleate buffer containing 1.50 M ammonium nitrate? (6 pts.)
41.7 mL

What mass of ammonium nitrate (F.W. 80.04) would be needed?

30.0 g

In the above example, how many -fold has the original buffer been diluted?

Prepare 100mL of a 0.1M potassium phosphate buffer of pH 6.5. You have K2HPO4 and KH2PO4 in solid/salt form available to mix with water to create this buffer. Final answer must include how many grams of each salt to mix with how many mL of water to prepare the buffer. I started this problem and got as far as using the Henderson-Hasselbalch equation and that the ratio of [HPO42-] to [H2PO4-] is 0.48 moles to 1 mole.

A liter of 0.050M pH 7.10 potassium phosphate buffer is needed for a certain experiment.

1) A liter of 0.050M pH 7.10 potassium phosphate buffer is needed for a certain experiment. The following four methods were proposed for the preparation of the buffer.
