I am given the solution of NaCl and it has a mass of 53.2 g and a molar mass of 58.44 g. I already know to how to find the number of moles for the entire solution, but I also need to find the number of moles for Na + ions. How exactly to I go about doing that? Thanks in advance!

once you know the number of moles, you can divide by the number of ions dissociated to get the number of Na+ ions. for example, if you know that you have (53.2/58.44) moles total, you know that you have (53.2/58.44) moles of Na because each mole of NaCl dissociates into one mole Na and one mole Cl.

 

for every mole of nacl, you get one mole of na.

it's a 1:1 ratio, because of the way it dissociates
