Hi Yash,


begin mathsize 14px style straight V subscript 1 equals straight V subscript 2 straight K straight q subscript 1 over straight q subscript 2 equals straight K straight q subscript 2 over straight q subscript 1 rightwards double arrow straight q subscript 1 over straight q subscript 2 equals straight R subscript 1 over straight R subscript 2 straight sigma subscript 1 over straight sigma subscript 2 equals fraction numerator straight q subscript 1 divided by 4 πR subscript 1 superscript 2 over denominator straight q subscript 2 divided by 4 πR subscript 2 superscript 2 end fraction equals straight q subscript 1 over straight q subscript 2 open parentheses straight R subscript 2 over straight R subscript 1 close parentheses squared straight sigma subscript 1 over straight sigma subscript 2 equals straight R subscript 2 over straight R subscript 1 end style

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
