Question

mole fraction of the solute in 1 molal aqueous solution is

Answer 1

Answer:

0.0177

Explanation:1 molal means 1 mole of solute on 1000g of solvent(here water cz solution is said aq.; m.wt=18)

so,

total moles = moles of solute (i.e 1) + moles of water (1000/18)

mole fraction= mole of solute / total moles  

                    = 1/1+55.5

                    = 0.0177
