Mass of an electron in grams `"_______________"`.

The gram atomic mass of an element is expressed in _______.

The ratio of charge to mass of an electron in coulombs per gram was determined by J.J. Thomson. He determined this ratio by measuring the deflection of cathode rays in electric and magnetic fields. What value did he find for this ratio?
