A sample of lead has a mass of 45.00 kg and a density of 1.130 104 kg/m3 at 0°C. (Assume the average linear expansion coefficient for lead is 2.900 10-5(°C?1).)
(a) What is the density of lead at 93.00°C? (Give your answer to four significant figures.) Did you accidentally divide or take the inverse in your calculation?
kg/m3
(b) What is the mass of the sample of lead at 93.00°C?
kg
