There is gas in the container under the piston. The piston was moved so that the volume of gas decreased by 3 times.

There is gas in the container under the piston. The piston was moved so that the volume of gas decreased by 3 times. How did the density of the gas change?

The density of the gas is found by the formula p = m / v, according to the condition, we are not told how the mass changes, so we take the mass as a constant value.
Then, with a decrease in volume and a constant mass, the density of the gas will increase.
