  1. Formula to be used:
    Molality = moles of solute / kg solvent

    Steps:
    #1. To do this, get the molar mass of Tin, using a periodic table. Fomula for Tin in Sn (look it up in the periodic table, and you'll see its mass).

    #2. After you get the mass of Tin, divide it by 5 g, and you'll have the moles of solute.

    #3. Finally, divide moles of solute to 95 g Copper. Of course, convert first grams to kilograms.

    Hope this helps :3
