A37.2-g sample of lead (pb) pellets at 20â°c is mixed with a 62.7-g sample of lead pellets at the same temperature. what are the final mass, temperature, and density of the combined sample? the density of pb at 200c is 11.35 g/cm^3.

Mass of sample is 99.9 g, density of ample is 11.35 and temperature of sample is

Explanation:

Mass is an additive property. Therefore mass of combined sample is summation of masses of two pellets.

Mass of combined sample = (37.2+62.7) g = 99.9 g

Density is an intensive property. Therefore density of combined sample of lead will be same as with density of Pb.

Density of combined sample = 11.35

Temperature is an intensive property. Therefore temperature of combined sample of lead will be same as with individual pellets.

temperature of combined sample =
