Substance has density 15.0g/cm^3 and weight 2.00 lbs. What is volume in gallons? (454g=1lb; 1.06qt=L)

---

Is this right so far?

V=Dm

V=15.0g/cm^3 X 908 g ( I CHANGED LBS TO GRAMS)

V=13620g/cm^3

  1. 454 gm = 1 lb

    1.06 qt = 1 L

    10^3 cm^3 = 1 L

    1 gal = 4 qt

    2.00 lb

    = 2.00 * 454 gm

    2.00 * 454 gm

    occupies

    2.00 * 454 / 15.0 cm^3

    2.00 * 454 / 15.0 cm^3

    = (2.00 * 454) / (15.0 * 10^3) L

    = (2.00 * 454 * 1.06) / (15.0 * 10^3) qt

    = (2.00 * 454 * 1.06) / (15.0 * 10^3 * 4) gal

    = 1.60 * 10^(- 2) gal.
