A sample of lead has a mass of 24.00 kg and a density of 1.130 104 kg/m3 at 0°C. (Suppose the average linear expansion coefficient for lead is 2.900 10-5(°C1).)
1) What is the mass of the sample of lead at 80.00°C?
2) What is the density of lead at 80.00°C? (Give your answer to four important figures.)
