You have a white crystalline solid, known to be one of the potassium compounds listed below. to determine which one, you measure its density. you measure out 15.57 g and transfer it to a graduated cylinder containing kerosene (in which these compounds will not dissolve). the level of liquid kerosene rises from 8.5 ml to 15.3 ml. calculate the density of the solid, and identify the compound from the following list.

the answer is d. 4

hope this

also the more points you give the faster your questions get answered

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
