  1. Sep 3, 2012 #1
    1. The problem statement, all variables and given/known data

    The average mass of an automobile in the
    United States is about 1.419 × 106 g.
    Express this mass in kilograms.

    2. Relevant equations



    3. The attempt at a solution

    Well I did dimensional analysis doing these exact steps to get the mass in kg:


    I
    1.419 x 10 ^6 g I 1 kg
    ---------------------------------------- = 1419 kg
    I 1000 g
    I



    *the I's and the --- are the railroad tracks thing for dimensional analysis conversion. sorry it looks weird but i don't know how to put properly put railroad tracks on the computer. :frown: . As u can see I got the answer of 1419 kg, is the answer correct? did i set it all up correct or no? :confused::frown:

    I assume that should read 1.419 × 106 g.

    There are 1000 grams in a kilogram so simply divide 1.419 × 106 by 1000..

    1.419 × 106 / 1 x 103

    = 1.419 × 103 kg or 1419 kg
