Answer :
Final answer:
To find the mole fraction of NH4NO3 in the solution, you need to calculate the moles of NH4NO3 and water and then divide the moles of NH4NO3 by the total moles of NH4NO3 and water in the solution.
Explanation:
To find the mole fraction of NH4NO3 in the solution, we first need to calculate the moles of NH4NO3 and water in the solution. The molar mass of NH4NO3 is 80.05 g/mol and the molar mass of water is 18.015 g/mol. Then, divide the moles of NH4NO3 by the total moles of NH4NO3 and water in the solution to get the mole fraction.
Mass of NH4NO3 = 39.1 g
Mass of water = 52.8 g
Moles of NH4NO3 = mass of NH4NO3 / molar mass of NH4NO3
Moles of water = mass of water / molar mass of water
Mole fraction of NH4NO3 = moles of NH4NO3 / (moles of NH4NO3 + moles of water)
