How would you prepare 1.00L of 0.13m solution of sugar, C12H22O11? The density of the resulting solution is 1.10g/mL.

m=molality

  • Chemistry - ,

    Use mass = volume x density to calculate the mass of 1000 mL of the final solution. Then use the definition of molality = mols/kg solution.
    I like to calculate the mass, then put molality into a single equation, which is,
    kg x m x molar mass = grams.
    You know kg, m, and molar mass. Calculate grams.
    Post your work if you get stuck or don't understand what I've done.

    I don't undastnd.
