1. The problem statement, all variables and given/known data If the mass of a hydrogen atom is 1.67*10-27kg and the mass of an electron is 9.1*10-31kh, how many electrons would be required to have a mass equivalent to one hydrogen atom? 2. Relevant equations 3. The attempt at a solution I tried dividing them into each other but I got some weird answer which didn't seem like it was right.
