A1-m3 rigid tank contains 10 kg of water (in any phase or phases) at 160 0c. the pressure in the tank is: a)-370 kpa b)- 618 kpa c)-2000 kpa d)-1618 kpa e)-738 kpa

Option C is the correct answer.

Explanation:

We have ideal gas equation,  PV = nRT

Volume of tank, V = 1 m³

Mass of water = 10 kg

Mass of 1 mole of water = 18 g = 0.018 kg

Number of moles,

Temperature, T = 160 °C = 160 + 273 = 433 K

Ideal gas constant, R = 8.314 JK⁻¹mol⁻¹

Substituting

      P x 1 = 555 x 8.314 x 433

      P = 2000000 Pa = 2000 kPa

The pressure in the tank is 2000 kPa

Option C is the correct answer.              

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

i need the answer to this too but idk it ; -;
