Answer:

Explanation:

Convert 55lbs to kg

(55 lb)*(453.6 g/lb) = 24948 g or 249.48 kg

Density of zinc = 7140 kg/m^3

Find the volume occupied by 249.48 kg:

  (249.48 kg)/(7140 kg/m^3) = 0.055 m^3

Density of silver = 10,490 kg/m^3

Mass of Ag in 0.055m^3:

  (0.055m^3)*(10,490 kg/m^3) = 577 kg

  • V_1=49.8mL
  • T_1=18°C=291K
  • T_2=83°C=356K

Using Charles law

\\ \sf\longmapsto V_1T_2=V_2T_1

\\ \sf\longmapsto V_2=V_1T_2\div T_1

\\ \sf\longmapsto V_2=\dfrac{49.8(356)}{291}

\\ \sf\longmapsto V_2=\dfrac{17728.8}{291}

\\ \sf\longmapsto V_2=60.9mL
