500 g sample of aluminium pellets specific heat capacity, Ask an Expert

Academics

5.00 g sample of aluminium pellets (specific heat capacity 0.89 J oC-1 g-1) and a 10.00 g sample of iron pellets (specific heat capacity 0.45 J oC-1 g-1) are heated to 100.0 oC. The mixture of hot iron and aluminium is dropped into a beaker containing 100 g of water at 15 oC. What is the final temperature of the liquid water? Heat capacity of liquid water is 4.18 J oC-1g-1; of ice 2.05 J oC-1 g-1; of steam 1.996 J oC-1 g-1; ?Hvap 40.7 kJ mol-1; ?Hfusion = 6.0kJ mol-1
