Asample containing 4.50g of o2 gas has an initial volume of 15.0l
what is the final volume, in liters, when each of the following changes occurs in the quantity of the gas at constant pressure and temperature?
a sample of 2.40g of o2 is removed.
express your answer to three significant figures.
v= l

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.)
