In a calorimetry experiment a 5.0g sample of metal is added to 80g of water. The metal was initially at 75oC and the water was initially at 10oC. When the process reached equilibrium, the final temperature was 29.2oC. What is the specific heat of the metal

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
