Answer 1
1 x 101 kg


This answer would imply that a chicken egg has a mass of approximately ten kilograms (22 pounds, about the size of a small dog). Chicken eggs are not normally this large. Thus, this cannot be the correct answer. return to top

Answer 2
1 x 102 kg


1 x 102 kilograms is equal to 100 kilograms. This is approximately the mass on an NFL linebacker. Chicken eggs are not normally as massive as a human. Because of this, answer 2 must be incorrect. return to top

Answer 3
1 x 10-1 kg


You cracked the question! 1/10 of a kilogram is equal to 100 grams, which is roughly the mass of an average chicken egg. return to top

Answer 4
1 x 10-4 kg


This is incorrect because 1 x 10-4 kilograms is equal to .0001 kilograms, or roughly the mass of a grain of brown rice; this is too small to be an egg, so answer 4 must be incorrect. return to top

What's this question really asking?

(a) Do you know how to deal with scientific notation?
(b) Do you know approximately how much a kilogram (kg) is?
(c) Do you know how massive a chicken egg is? return to top
