1. To determine the potassium content of a sample, 1.275 g of the sample was dissolved in water and reacted with sodium tetraphenylborate, NaB(C6H5)4. This reaction produced the insoluble precipitate potassium phenylborate, KB(CHs)4 (FM = 358.33 g/mol). The potassium phenylborate precipitate was weighed and had a mass of 0.955 g. Calculate the percentage by mass of K (FM = 39.098 g/mol) in the sample. (Inspired by problem 7-6 in the Harris text). %3D
