the radius of a chlorine atom is 99 pm and its mass is 5.89 X 10^-23 grams what is the density

  • general chemistry - ,

    I am assuming that 99pm means pico meters, so 99pm = 99 x 10^-7 cm

    D=mass(g)/volume(cm3)

    Plug in the value for radius into the equation to solve for the volume which will have units of cm^3

    v=4/3πr^3

    Since density=mass(g)/volume(cm3),

    Solve for density,

    D= (5.89 X 10^-23 g/volume calculated in cm^3)

  • general chemistry - ,

    so to get volume, you do v=(1.33)*3.14*99e-7^3????

  • general chemistry - ,

    Yes.

    But, I gave you the wrong units for 99pm in cm, it should be 99x10^-10. I apologize about that
