The standard atmospheric pressure is 101 kPa.

A steel container initially contains 453 kg of water. You then force additional water in and get the pressure to 68,707 kPa. The tank volume expands by 1%.

How many kg of water is added?

Answer :

The amount of water added to a steel container, use the ideal gas law PV=nRT and consider the expansion of the tank volume, Using this approach, the amount of water added is 19.18 kg.

Calculating the amount of water added to a steel container To determine the amount of water added, we can use the ideal gas law, PV=nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

Since the volume expands by 1%, we know that the final volume is 1% larger.

We can calculate the initial volume by dividing the mass by the density of water. Then we can find the final volume and use PV=nRT to calculate the number of moles. Finally, we can convert moles to kilograms by multiplying by the molar mass of water.

Using this approach, the amount of water added is approximately 19.18 kg.
