The internal energy : 1310.43 kJ/mol
<h3>Further explanation</h3>
Internal energy (ΔE) can be formulated for Calorimeter :

C= the heat capacity of the calorimeter
Δt=36.2-25.68=10.52°C

- mol butane(MW=58,12 g/mol)

- the internal energy (ΔE) in KJ/mol

They’re different in regards to the fact that nebulae are not actively burning while stars are
Answer:
<h2>3.31 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 23.2 g
volume = final volume of water - initial volume of water
volume = 62 - 55 = 7 mL
We have

We have the final answer as
<h3>3.31 g/mL</h3>
Hope this helps you
