A concentrated solar power plant stores thermal energy in a large tank of molten salt to generate electricity.

a.

Write down the equation which links density (ρ\rhoρ), mass (mmm), and volume (VVV).

[1]
b.

The storage tank holds 7,200 m37,200\text{ m}^37,200 m3 of molten salt. The density of the molten salt is 1,890 kg/m31,890\text{ kg/m}^31,890 kg/m3. Calculate the mass of molten salt in the storage tank. Give your answer in standard form.

c.

Write down the equation which links energy transferred (EEE), power (PPP), and time (ttt).

[1]
d.

The stored heat can drive steam turbines to provide 2.4×108 W2.4 \times 10^8\text{ W}2.4×108 W of electrical power for a maximum of 8 hours8\text{ hours}8 hours. Calculate the maximum energy that can be transferred by these generators. Give your answer in standard form.
