3.5 x 10^22 moles of carbon are there in a 0.70 g (3.5 carat) diamond.
Explanation:
In case of diamond, the number of atoms is the same as the number of molecules.
Answer:
-411 kj
Explanation:
We solve by using this formula
∆U = ∆Q + ∆W
This formula is the first law of thermodynamics
Change in internal energy U = +241
Heat gained by system Q = 652
Putting the value into the equation
+241 = 652 + W
Workdone = 241 - 652
Workdone = -411 kj
Since work done is negative it means that work was done by the system
