the mass of cylinder one is 1.35 times the mass of cylinder two, and the volume of cylinder one is 0.792 times the volume of cylinder two. If the density of cylinder one is 2.70 g/cm3 what is the density of cylinder two?

  1. density is mass/volume.
    So, twice the mass, twice the density.
    twice the volume, half the density. So, for cylinder 2, we have

    (1/1.35) / (1/.792) * 2.70 = 1.584

  2. d1 = m1/v2 = 2.70 g/cc
    m1 = 1.35*m2 so
    m2 = m1/1.35

    V1 = 0.792*v2 so
    v2 = v1/0.792

    d2 = m2/v2
    d2 = (m1/1.35)/( v1/0.792)
    d2 = m1/1.35 x 0.792/v1 but
    m1/v1 = 2.70
    then d2 = 2.70 x (0.792/1.35) = ?
    Check this.
