Question

calculate the mole fraction of solute in its 1 molal aqueous solution

Answer 1

2 molar aqueous solution means 2 moles of the solute in 1000g of water. If 18g of water is 1 mole , then 1000g of water will be 55.55 moles. So the mole fractionof a solute in a solvent is given by : number of moles of solute/ (number of molesof solute + number of moles of solvent).
