Calculate the mole fraction of total ions in an aqueous solution prepared by dissolving .400 moles of MgCl2 in 850.0g of water.
mole fraction =amount solute(in mols) /total amount of solute and solvent (in mols)
so wouldn't it be .400/ .400+ 47.2 which is the moles of water?

There are three ions per MgCl2 formula unit. Moles ion=3*.4 moles
molefraction=3*.4/(.4+47.2)
molefraction=3*.4/(.4+47.2)
