Question

Calculate the mole fraction of solute in its 2 molal aqueous solution .

Answer 1

2 molar aqueous solution means 2 moles of solute in 1000g of water.if 18g of water is 1 mole then 1000g of water will be 55.55 moles.so the mole fraction of solute in a solvent is given by;number of moles of solute/(number of moles of solute /number of moles of solvent)
    
    so,
        2/(2+55.55)=0.03475
