The mass either decreases or increases
the density increases
When mass increases and volume stays constant, the density increases. When volume increases and mass stays constant the density decreases. When they both change, then the density will depend on the rate of change of mass and the rate of change of volume.
The density decreases by half. You find the answer by knowing that density is equal to mass divided by the volume. If the mass stays constants and the volume is doubled, then the density is halved.

If mass stays the same and density decreases, then the volume must increase. This is because density is mass divided by volume, so if density decreases while mass remains constant, the volume must increase to maintain the same mass.

If the volume of an object decreases but its mass remains the same, the density of the object will increase. Density is calculated as mass divided by volume, so if the volume decreases while the mass stays constant, the overall density will be higher.
If the volume of a gas increases, the density of the gas will decrease. This is because density is mass divided by volume, so as the volume increases while the mass stays constant, the density will decrease.
