N Example 3) The concentration of an aqueous
solution of glucose (180 g/mol) is 0.500 mol/L and
its density is 1.05 g/mL. Calculate the molality of
the glucose.​

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
