Adrop of water weighing 0.48 g is vaporized at 100 ? c and condenses on the surface of a 55-g block of aluminum that is initially at 25 ? c. if the heat released during condensation goes only toward heating the metal, what is the final temperature in celsius of the metal block? (the specific heat capacity of aluminum is 0.903 j/g ? c.

Hi, the solution would be like this for this specific problem:

(2257 J/g) x (0.48 g) = 1083.36 J 

(1083.36 J) / (0.903 J/g ∘C) / (55 g) = 21.81°C change 

25°C + 21.81°C = 47°C

I hope this helps and if you have any further questions, please don’t hesitate to ask again. 

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
