An experiment in chm 2045 requires students to prepare a 1. 0 m aqueous solution of potassium phosphate. Jennifer fills a 1. 0 liter volumetric flask to the calibration line with water. She then weighs out 212. 3 g of potassium phosphate and adds it to the volumetric flask. Joe weighs out 212. 3 g of potassium phosphate and adds it to a 1. 0 liter volumetric flask. He then fills the volumetric flask to the calibration line with water. Which student has correctly prepared a 1. 0 m aqueous solution of potassium phosphate?.
