Answer

Explanation:

Step1: Calculate the value of the weight

$3.136\times 10^{3}=3136$

Step2: Analyze each option

  • Grams: A newborn baby's weight in grams is reasonable around 2500 - 4500 grams. 3136 grams is in this range.
  • Ounces: 1 ounce is approximately 28.35 grams. So 3136 grams is $\frac{3136}{28.35}\approx110.6$ ounces. Newborn weights are not usually expressed in such large - number of ounces.
  • Pounds: 1 pound is 453.592 grams. So 3136 grams is $\frac{3136}{453.592}\approx6.9$ pounds. While newborns can be around 6 - 9 pounds, the scientific - notation value is more commonly associated with grams in this context.
  • Tons: 1 ton is 907185 grams. 3136 grams is a tiny fraction of a ton and is not a reasonable unit for a newborn's weight.

Answer:

grams
