What does (Na+Cl-)n mean? Does it mean specifically a lattice so ions not paired? Or does it mean like NaXClX so any number of Na and Cl ions paired up and in a 1-1 ratio?
I was told that the number of moles is 'dimensionless', does this mean that the dimension of Molar mass is simply 'mass and hence the unit g/mol can be expressed as equal or proportional to the dalton?
