Splet(c) the mass of AgCl precipitated from the mixture is 6.435 g. Determine the mole fraction of LiCl in the mixture. Solution: 1) The mass of KCl in the mixture will be our unknown, 'x.' This leads a description of the mass of NaCl present and the mass of LiCl present: mass of NaCl in the mixture ---> 2.370 − x SpletAnswer (1 of 2): This question is not clear! Let’s assume that 0.1 solution means 0.1M solution. 0.1 M solution = 0.1 mole of NaNO3 in 1 L of solution. Given 0.1 mole in 1L of the solution, how many moles do you need for 100 L of solution? X Then change X moles of NaNO3 into mass. Splet21. nov. 2024 · The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10-24 grams.
