Expert Answer

Step 1

Given:

Mass of lead (Pb) pellets at 27°C = 39.3 g

Mass of lead (Pb) pellets = 66.3 g.

Step 2

Calculation for final mass:

Total mass = Mass of lead (Pb) pellets at 27°C + Mass of lead (Pb) pellets

Total mass = 39.3 g + 66.3 g = 105.6 g

Step 3

As lead pellets are at same temperature. So, temperature r...
