The vector cross product is anticommutative, means that while evaluating the cross product of two vectors it does matter which vector you treat as first and which as second. Because using right hand rule to find the direction of resultant vector depends upon which vector you start with.

Hence A X B ≠  B X A, but A X B = - B X A

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?
