A radioactive metal atom decays by emitting an alpha particle, which is a helium nucleus. The
alpha particles are collected as helium gas. A sample of helium with a volume of 12.05 mL was
obtained at 765 mmHg and 23 °C. How many atoms decayed during the period of the
experiment?

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.)
