Question

The average mass of a car in the US is 1.440 x 10^6 g. Express this mass in kg.

Answer 1

Average mass of acar in the US (in kg) = 1440 kg

Step-by-step explanation:

Average mass of a car in the US (in g) = 1.440 × 10⁶ g

Mass in kg:

`\rm 1 \: g = {10}^( - 3) \: kg \\ \\ \rm 1.440 * 10^6 \ g = 1.440 * 10^6 * {10}^( - 3) \ kg \\ \\ \rm = 1.440 * 10^(6 - 3) \ kg \\ \\ \rm = 1.440 * 10^3 \ kg \\ \\ \rm = 1.440 * 1000 \ kg \\ \\ \rm = 1440 \ kg`
