<span>C6H12 = 6x12 + 6x1 = 78.
The equation indicates that 2x78 = 156g benzene will produce 6542kJ.
Using proportions you can then calculate that
x/6542kJ = 7.9g / 156g
x = 331.3kJ = 331300J.
heat = mass x ΔT x 4.18J/g°
ΔT = 331300J / (5691g x 4.18J/g°) = 13.9°
final temp = 21 + 14° = 35°C</span>
Answer:

C. It stays the same as energy is added.
Answer:
0.052 M.
Explanation:
Hello!
In this case, since the molarity is computed by dividing the moles of the solute by the volume of the solution in liters (M=n/V), we first need to compute the moles in 5.025 grams of NaOH as shown below:
![n=5.025g*\frac{1mol}{40.0g}\\\\n=0.126mol](https://tex.z-dn.net/?f=n%3D5.025g%2A%5Cfrac%7B1mol%7D%7B40.0g%7D%5C%5C%5C%5Cn%3D0.126mol)
In such a way, we compute the molarity as show below:
![M=\frac{0.126mol}{2.4L}\\\\M=0.052M](https://tex.z-dn.net/?f=M%3D%5Cfrac%7B0.126mol%7D%7B2.4L%7D%5C%5C%5C%5CM%3D0.052M)
