Problem

When a 45.0 g sample of an alloy at 100.0 °C is dropped into 100.0 g of water at 25.0 °C, the final temperature is 37.0 °C. What is the specific heat of the alloy? The specific heat of water is 4.184 J•g-1•°C-1

a) 0.423 J•g-1•°C-1

b) 1.77 J•g-1•°C-1

c) 9.88 J•g-1•°C-1

d) 48.8 J•g-1•°C-1
