Hello. i did not understand how to find these answers. "you will need to determine how many of each ion you will need to form a neutral formula wunit (compoundc)." i have to find the cation lds, anion lds, algebra for neurral compund, and ionic compound lds for k +f mg+i be+s na+o ga+s rb+n you for my.

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
