Homework Help: Please Help with density!

  1. Apr 20, 2009 #1
    A 100 cm^3 container has 4 g of an ideal gas in it at 250 kPa. If the volume is changed to 50 cm^3 and the temperature remains constant, what is the new density in kg/m^3.

    Any help would be greatly appreciated to help me understand! Thanks

    Density is mass/volume
    What have you changed, what stays the same?
