Reference no: EM13845673

Question: You have a white crystallime solid, know to be onenofnthe potassium compounds listed below. To determine which, you measure its density. you measure out 18.82 g and transfer it to a graduated cylinder containing kerosene( in which those compounds will not dissolve). The level of liquid kerosene rises from 8.5 ml to 15.3ml. Calculate the density of the solid and identity the compound from the following list.

KF, d=2.48 g/cm3

KCl, d=1.98 g/cm3

KBr, d=2.75 g/cm3

KI, d=3.13 g/cm3
